Summary: 20080411 OS X beta won't launch on PPC 10.4

Initial Comment:
Something's not right with the OS X version of the new beta (drjava-20080411-1951-r4436-osx.zip).  The zip file unpacks with no problems, but when I try to launch the application on a powerbook there's a little bit of finder animation, but then nothing happens.  The jar file does launch and appears to work just fine, so it looks like a problem with the OS X application wrapper.

Configuration: Powerbook G4, OS X 10.4.11.

[DrJava] [ drjava-Bugs-1926776 ] DynamicJava throws NullPointerException

Summary: DynamicJava throws NullPointerException

Initial Comment:
At the end of the following interactions, DynamicJava throws a NullPointerException (see Stack Trace 1 below), even though it should print "null".

Example 1:

Welcome to DrJava.  Working directory is /Users/Shared/drjava
> import java.lang.ref.WeakReference;
> WeakReference<String> wref
> String s = "foo"
> wref = new WeakReference<String>(s);
> wref.get()
"foo"
> wref.clear()
> wref.get()




After clearing the weak reference, WeakReference.get() returns null. The return value of wref.get() is null; therefore, the second call to wref.get(), the one that throws the exception, should produce the same result as 


Welcome to DrJava.  Working directory is /Users/Shared/drjava
> null
null




Furthermore, I have noticed additional strange behavior after wref.clear(). For example:

Example 2:

Welcome to DrJava.  Working directory is /Users/Shared/drjava
> import java.lang.ref.WeakReference;
> WeakReference<String> wref
> String s = "foo"
> wref = new WeakReference<String>(s)
java.lang.ref.WeakReference@8523a0
> wref.get()
"foo"
> wref.clear()
> Boolean boo = new Boolean(wref.get()==null)
> boo
Static Error: Undefined name 'boo'

Why is 'boo' not recognized?

When I ran the example 2 on a "fresh" DrJava, one that had not experienced the NullPointerException from example 1, I got another NullPointerException, the one shown in Stack Trace 2 below. Apparently "Reset Interactions Pane" is not enough to completely reset DynamicJava; the InteractionsPane never recuperated from the NullPointerException in example 1.

Another example:



Example 3:

Welcome to DrJava.  Working directory is /Users/Shared/drjava
> import java.lang.ref.WeakReference;
> WeakReference<String> wref
> String s = "foo"
> wref = new WeakReference<String>(s)
java.lang.ref.WeakReference@8523a0
> wref.get()
"foo"
> wref.clear()
> (wref.get()==null)
> 

Why does the comparison not produce any output? It should produce

> (wref.get()==null)
true
>

Again, if I ran this on a "fresh" DrJava, I got the NullPointerException shown in Stack Trace 2.


A final example:



Example 4:

Welcome to DrJava.  Working directory is /Users/mgricken/Documents/Java
> import java.lang.ref.WeakReference;
> String s = "foo"
> WeakReference<String> wref = new WeakReference<String>(s)
> wref.get()
"foo"
> wref.clear()
> boolean b = true
> b
true
> b = (wref.get()!=null)
> b
true
> 

The value of b did not change. The result at the end, of course, should have been

> b = (wref.get()!=null)
> b
false
> 

Again, if run on a "fresh" DrJava, I got the NullPointerException in Stack Trace 2.

Summary: Dr. Java constantly crashes when getting Null Pointer except

Initial Comment:
I have version 20080106-0744 running java version 1.6.02 Dr Java keeps blocking the run/test features when I get a null pointer exception. This normally occurs the second time I get the exception. The only way to get my program running again is to quit/restart Dr. Java. When debugging this is slows me down a lot. Thanks for the great program otherwise!

Summary: private constructors in classes are accessible

Initial Comment:
In the singleton pattern where the constructor of the singleton class is marked private, the interactions pane allows the private constructor to be accessed even when the "accessing private members of classes" option is turned off.

Summary: Indent Error with Enums

Initial Comment:
When enum constants' methods are overridden, Dr Java auto-indents improperly, for example:

public enum E {
    A {
        public int getValue() {
            return 1;
        }
    }, 
        B {
            public int getValue() {
                return 2;
            }
        },
            C {
                public int getValue() {
                    return 3;
                }
            };
            public abstract int getValue();
}

This should simply be

public enum E {
    A {
        public int getValue() {
            return 1;
        }
    }, 
    B {
        public int getValue() {
            return 2;
        }
    },
    C {
        public int getValue() {
            return 3;
        }
    };
    public abstract int getValue();
}

Summary: "Test Project" error when loading classes in packages

Initial Comment:
Important note: 
Bug seen in version 20080312-1948 revision 4395.
Bug does not occur in version 20080124-1942

If you test your code using the "Test Project" button, the following error is generated whenever it attempts to load a class that is in any package other than the default package:

"Testing works only on valid class files"
"The class file for subDir/MyClass2 in source file C:\[etc, etc]\src\subDir\MyClass2 cannot be loaded.  
When DrJava tries to load it the following error is generated:
java.lang.NoClassDefFoundError: Illegal name: subDir/MyClass2"

Above, the class MyClass2 is in the subDir package, *but is not instantiated during testing*.

The actual testing appears to successfully complete however. 

Also, testing each test file individually by hand, will result in all test files completing succefully with no errors shown.

The attached code contains a simple example that shows the above error.   It also includes two more test files that can be used to show that the error also occurs under similar constraints.

Summary: Add icons for all buttons

Initial Comment:
At present, not all the buttons on the UI have icons associated with them, e.g. "compile project", "Reset", "Run", "Test project", and "Javadoc".

When switching off of Metal look-and-feel, buttons in the same group do not have lines between them, making the buttons hard to distinguish from each other.  For instance, it looks like there is a single button called "Run test Javadoc" rather than three separate buttons.

The Windows standard is to always have an icon on every button, which helps to separate one button from another (see e.g. IE).

This would make non-Metal look-and-feel be much more palatable on Windows machines, for example.

Summary: Cannot instantiate inner class in Interactions pane

Initial Comment:
Important note:  problem seen in version  20080124-1942 but appears to be fixed in version 20080312-1948 revision 4395


Consider the following class with a nested class (problem exists for inner classes too):

public class OuterClass {
  public static class InnerClass {
  }
  
  public InnerClass makeIt() {
    return new InnerClass(); 
  }
}

If you try to run the following lines in the Interactions pane, the first will succeed but the rest will fail with the error
"Static Error: Name is ambiguous"

OuterClass oc = new OuterClass();  // this line ok in Interactions pane

OuterClass.InnerClass in1 = new OuterClass.InnerClass(); // fails in Interactions pane

OuterClass.InnerClass in2 = oc.makeIt(); // fails in Interactions pane

The above code will run just fine if compiled and run normally, e.g. in a test method.

The attached zip file has a project with the above code and a test file that shows that it works when compiled and run normally.

Summary: Separate Memory Preferences, Better Out of Memory Errors

Initial Comment:
We should separate out the maximum (-Xmx) and initial (-Xms) memory sizes from the "JVM Args for Main JVM" and "JVM Args for Interactions JVM".

This involves making sure that the "JVM Args for Main JVM" and "JVM Args for Interactions JVM" do not contain -Xmx and -Xms arguments, and that the maximum amount is not less than the initial amount.

Then we can respond better to exceptions like
java.lang.OutOfMemoryError and com.sun.jdi.VMOutOfMemoryException and directly suggest increasing the amount of heap space.

Summary: ArrayIndexOutOfBounds in Find All

Initial Comment:
I'm getting this error in a recent build when I switch to a "Find All" tab.  I only have 5 tabs open, so I would expect the correct index to be 4 here, not 5.

Summary: Apple menu items broken in Leopard

Initial Comment:
A bug I've noticed and haven't been able to figure out: in OS X 10.5, when DrJava is the active application, I can't launch "System Preferences" and "Software Update" from the Apple menu.  These apps will attempt to open and immediately crash.  I don't see this behavior when launching the apps in any other way, including from the Apple menu of NetBeans or a simple Java app built in XCode.

The log messages from the crashing app:

3/5/08 10:04:09 AM System Preferences[16234] No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting 
3/5/08 10:04:09 AM com.apple.launchd[108] ([0x0-0x4e24e2].com.apple.systempreferences[16234]) Exited with exit code: 1
