Summary: "Select Built Directory" dialog should follow lnk on Windows

Initial Comment:
"Select Built Directory" dialog should follow .lnk on 
Windows, if that .lnk points to an actual folder.  Right 
now it seems to display the item but one cannot go into 
the folder by double-clicking it.

Initial Comment:
The java source files with annotations are compiled 
without error, but the compiled classes bear no 
annotation information.

It seems that the compiler should add "-source 1.5" 
argument to the javac compiler, but I found no 
preference to set it.

[DrJava] drjava-20040825-2108 released

[Moez A. Abdel-G. <mo...@cs...>]

This release of DrJava is a candidate stable release.
The release includes some new features and further
more bug fixes. We have added a directory chooser
that uses a tree view of the file system, support to
compile and test entire DrJava projects, support for
auxiliary and external files in projects, more con-
sistency in the behavior and look of the definitions
pane and interactions pane, support in the Interact-
ions pane for the new '&' Java 1.5 generics syntax,
and, finally, added also an 'Advanced' language level.
We fixed issues that prevented running a new DrJava
from within DrJava, as well as issues in the Inter-
mediate language level.

Summary: Incorrect indentation of nested if

Initial Comment:
Nested if statements without braces are auto-indented incorrectly:

class Test {
  void test(int i) {
    int j = -1;
    if (i > 0) 
      if (i > 1)
      j = 3;
    else
      j = 5;
  }
}

The "else" should align with the inner "if" following the dangling-
else rule of Java syntax.

Summary: NoClassDefException - running drjava inside drjava (Windows)

Initial Comment:
On the windows platform (1.4.2 and 1.5 build 60), I
open drjava and run DrJava from the interactions (or
from running project) and it says it can't find a
windows specific class in what I assume should be the
platform.jar.

This error does not happen when running from the
command line or when running the jar.  Could it be a
classpath issue?

This error was introduced sometime after the end of July.

Submitted By: Jonathan Lugo (jeloguy15)

Summary: Error displayed on startup even if compiler was found

Initial Comment:
Story:
The user has 2 versions of the SDK installed on their
computer at the same time (e.g. j2sdk1.4.2 & jdk1.5.0).
 Java 1.5 is the default JVM (either because of the
$JAVA_HOME variable in Linux/Unix, or because it was
the last one installed in Windows), but the user runds
DrJava in the other one (i.e. j2sdk1.4.2).

When DrJava starts up it says that it couldn't find a
valid tools.jar.  Even when the user selects the
correct toos.jar, it again warns that this version is
incompatible.

When the user has no choice but select 'No', the
correct compilers still show up in the compilers menu
making the message seem unnecessary.

Problem:
The same message is displayed when EITHER the compiler
OR the debugger cannot be loaded correctly.  So if the
compiler loads well but the debugger doesn't, the user
will still think drjava cannot find the compiler.

Partial Solution:
I created two error messages: one if the compiler fails
and one if the debugger fails.  These messages explain
more accurately what's going on.  

** I'm leaving this bug open because I think we should
look into why the debugger isn't loading when the
correct tools.jar is given.

Summary: Cancel button when running JUnit tests

Initial Comment:
It would be nice if we had a cancel button when running
the JUnit tests. They already are running under the
Slave JVM; if we had a second slave JVM for JUnit, and
added a cancel button, we could reset that JVM, killing
the JUnit tests.

Just a feature request I've had since we gained the
ability to test all - it would be nice to be able to
break our, or at least, have an option to stop running
tests after a test fails, so that if an early test
fails you don't have to sit there and wait for all the
other tests to finish before you can analyze what failed.

Summary: Hotkeys for next/previous error

Initial Comment:
Currently, whenever you are using one of the error
panels (JUnit, Javadoc, Compiler errors, CVS diffs),
there are two little buttons on the right hand side to
go to the next and previous error, but there is no
hotkey to do this. 

We have nearly every key bound to a hotkey. E is not.
It would be logical to view the next error, when an
error list pane is active, by pressing CTRL + E and the
previous error by pressing CTRL + SHIFT + E.

Assigned to: Nobody/Anonymous (nobody)
Summary: Line-wrapped editing of multi-line comments

Initial Comment:
When editing a multi-line comment, it would be
convenient if the editor's behavior changed: when a
preset width is reached, the editor inserts a newline
before the last word break and moves the next word and
cursor to the next comment line.  When deleting the
beginning or end of a line, the comment is
automatically re-wrapped.

For example ("|" indicates cursor):

/*
 * This is my comment that has a rather long line t|
*/

When typing continues, this is the result:

/*
 * This is my comment that has a rather long line 
 * that just keeps going ...|
*/

If the user removes the word "long", this is the result:

/*
 * This is my comment that has a rather |line that
 * just keeps going ...
*/

If the user then moves the cursor to the end of the
word "that" and presses delete, here is the result:

/*
 * This is my comment that has a rather line 
 * that|just keeps going ...
*/

Of course, since newlines would apparently be
hard-coded into the source file, there is an ambuguity:
what if the user introduces his own newline:

/*
 * This is the first line.|
 * This is the second line.
*/

When the user keeps typing, does he get this:

/*
 * This is the first line.  I've decided to add 
 * a bit more text.| This is the second line.
*/

Or this:

/*
 * This is the first line.  I've decided to add 
 * a bit more text.|
 * This is the second line.
*/


Resolving that ambiguity is a key task necessary to
make this work.  In either case, though, it wouldn't be
that hard for the user to to add a desired newline or
remove an unwanted one.

Summary: Save As behavior strange when modified version of file open

Initial Comment:
Recently, behavior was added so that the user could use
"Save As" to overwrite a file that was already open in
DrJava.  However, this leads to strange behavior if the
file you are overwriting has been modified in DrJava. 
In this case, you are promped to make sure you do in
fact want to overwrite the open file, and then you are
prompted that the file being overwritten has been
modified, and would you like to save it?  

If you select that you do not want to save it, the old
modified version is overwritten by the new version, as
expected.

If you select cancel, you get 2 copies of the file side
by side, one that is the old version, and one that is
the new version.  This may be the desired behavior--I'm
not sure.  

But if you select that you would like to save it, any
modifications you have made are not actually
saved--your modified version is overwritten with the
version you are calling "save as" on.  This seems like
a definite problem.

Perhaps a simpler way to handle this would be to only
display 1 dialogue box that reads "This file is already
open in DrJava and has been modified.  Are you sure you
want to overwrite it?"

Summary: Unexpected ClassCastException when passing array for varargs

Initial Comment:
Say you have a method that uses variable arguments such
as: 

public void run(int...) { ... }

if you call the method using the traditional array
rather than multiple arguments in the interactions pane
such as:

run(new int[] {1,2,3});

DynamicJava throws a ClassCastException.  When the same
code was compiled in the definitions pane, it worked well.

Summary: NullPointerException when passing null paramter

Initial Comment:
If in the interactions pane you call on a method
incorrectly, normally you get the message:

Error: No '...' method in '...' with arguments: (...)

But if you pass any null parameters either into a
non-existent method or into an existing method with the
wrong number/types of arguments, dynamic java throws a
NullPointerException instead of showing the error
message.  

Even though there is no stack trace displayed for this
exception in the interactions pane, the user may still
think that the exception is being thrown from within
the method and that the method still exists.

Summary: NullPointerException in parser/checker for elementary LL

Initial Comment:
Compiling the following elementary level program
generates a null pointer exception (or other spurious
behavior):

abstract class List {
  abstract int length();
  abstract List insert(Comparable o);
}

class NonEmpty extends List {
  Object first;
  List rest;
  int length() { return 1 + rest.length(); }
  List insert(Comparable o) {
    if (o.compareTo(f) <= 0) return new NonEmpty(o, this);
    return new NonEmpty(f, rest.insert(o));
  }
}

class Empty extends List {
  int length() { return 0; }
  List insert(Comparable o) { return new NonEmpty(o,new
Empty());      }
}

Note that this program has a syntax error.  The
variable "f" in NonEmpty should be "first".  

When I tried to reproduce the bug, compiling the
program (three
separate files) generated .java files with syntax
errors.  These
files suddenly appear in the open files list which is
very disconcerting.

P.S. We need to add Language Levels as a bug category.

Once in a while just after compiling and I click on the

I can still move it around because I notice the blocks

The bug doesn't show up everytime, but it happens every

Summary: Parameterized class that implements several interfaces

Initial Comment:
If you wish to parameterize a class with a type T, that
implements the two interfaces Comparable and
Serializable, there is a problem in distinguishing
between a second parameterized class S that you might
want to have. Sun decided to use the "&" when
implementing several interfaces here. And they are
using the extends keyword. This is all legal syntax in
the Java 1.5 beta 3 that we are now using. But the "&"
is not currently supported in DynamicJava.

Example;

import java.io.Serializable;

public class A <T extends Comparable<T> & Serializable, S>

Summary: Losing data with new file management

Initial Comment:
I have been using the newest DrJava version from the
Cvs repository and I have lost my programs more than once.

What happens is that I try to save a file that already
exists, and it asked me if I wanted to overwrite it.
I said yes.
Then it claimed it couldnt find the specified file, and
suddenly the document was empty. I reloaded the file
(which did exist), but it was now EMPTY.

Most annoying.

I have also been getting that huge blue button in the
file navigator on more than one occassion.

Initial Comment:
Sorry to bombard you guys, but after trying to quit
DrJava from a session with two meaningless untitled
files (which I was using to test the Replace All
behavior), I got a NullPointerException after refusing
to save the second file.  Sadly, I have so far been
unable to reproduce the bug, so it might be a fluke,
but I thought I'd submit it for the sake of thoroughness.

As an interesting side-note, performing "Close" just
doesn't do anything, but "Close All" (which also
happens when I try to quit) causes a similar exception
(at DefaultSingleDisplayModel.closeAllFiles, line 383).

Suppose you replace a string with a shorter string,
choosing "Replace All" with "Search All Documents"
checked.  The result is that the old caret position is
out of bounds, which is not an error, but it is

(there are a few more, but they're event pump methods
and not very interesting.)
Anyway, this is ugly.  It looks like it's
AbstractDJPane's job to catch this and just choose some
unoffensive caret position (probably the end, or maybe
if the offending index is somehow negative you could
make it the beginning, though it doesn't matter much).

Initial Comment:
Performing a "replace all" will occur one too many
times in the current document only.  For example, if
you have two documents open, which both contain only
"int" and perform a search/replace "int" with "uint"
then the current document will contain "uuint" and the
other document will (correctly) contain "uint" -- for
some reason, the current document is search/replaced
twice, but other documents are not.
