Re: [Sablevm-developer] Code indenter / Uncompilable classes

[Ian R. <ir...@cs...>]

Hi,

Here's a summary of where I'm up to. I'm trying my best to build the
sablepath-classes with a standard SuSE 7.2 set up. To build the .class
files I'm running "find src -name '*.java'|xargs jikes +E -classpath
/home/ian/sable/sablepath-classes/src:/home/ian/old-classpath". Jikes
version 1.2. The story so far:

> src/java/util/jar/JarEntry.java
> src/java/util/jar/JarFile.java
> src/java/util/jar/JarInputStream.java
> src/java/util/jar/JarOutputStream.java
> src/java/net/JarURLConnection.java

The jar stuff relies on java/util/zip which for some reason isn't in the
classpath repository. If it were I'm confident this would build.

> src/java/net/URLClassLoader.java

Built fine for me. Possible issues with the Jar stuff tho'.

> src/java/util/IdentityHashMap.java

The clone method needs to have "throws
java/lang/CloneNotSupportedException" appended. I guess Object.clone was
updated and this file was missed during the update.

> src/javax/swing/plaf/BorderUIResource.java

Wouldn't compile so moved out of the build tree. Issues mainly with a
border package.

> src/javax/swing/GrayFilter.java

Compiled fine when the body of createDisabledImage was altered to return
null; and filterRGB's result was cast to an int.

> src/javax/accessibility/AccessibleText.java
> src/javax/accessibility/Accessible.java
> src/javax/accessibility/AccessibleHypertext.java

There's clearly issues with javax/accessibility. I moved these files.

> src/javax/accessibility/AccessibleComponent.java
> src/javax/accessibility/AccessibleSelection.java

Compiled fine for me, but failed when the other files were moved.

> src/gnu/javax/swing/plaf/gtk/GtkIconFactory.java

Failed most notably because java/swing/plaf/gtk/Icon was misssing,
therefore moved.

> src/gnu/javax/swing/plaf/gtk/GtkSliderUI.java
> src/gnu/javax/swing/plaf/gtk/GtkLookAndFeel.java
> src/gnu/javax/swing/plaf/gtk/GtkRadioButtonUI.java
> src/gnu/javax/swing/plaf/gtk/GtkBorders.java
> src/gnu/javax/swing/plaf/gtk/GtkCheckBoxUI.java

Failed for lots of reasons, javax/swing/plaf/basic and
javax/swing/border not being present being one of them, files moved.

I'm running a slightly older version of Jikes and things appear to be
fine. I'm keen to keep using this older version of Jikes too, until
someone points out a really good reason to upgrade.
 
In summary, everything is there and building except Swing and the Jar
related stuff. As some of the core stuff relies on the Jar stuff I'm
keen we get that working. I'll e-mail the maintainer and hopefully find
out when the stuff will appear in the classpath CVS repository. The
Swing stuff isn't critical to me, and it appears very incomplete. I
suggest we move it out of the code tree for the time being.

Finally, the way I'm building the code at the moment puts all the
pressure on jikes. Should we build a set of makefiles, configure, etc..
?

All the best,

Ian Rogers
