natClass.cc, java::lang::Class::initializeClass() problems

[Marco Trudel <mtrudel at gmx dot ch>]

Hello all

I'm trying to use AWT/Swing from a Sun 1.4.2_13 JRE. I can successfully 
compile a minimal AWT application with AWT/Swing from Sun instead of GNU 
classpath. When running the compiled binary, I get:

Exception in thread "main" java.lang.NoClassDefFoundError: 
sun.awt.windows.WComponentPeer
   at 
java.lang.Class.initializeClass(/foobar/GCC-source/libjava/java/lang/natClass.cc:719)
   at java.awt.Component.initIDs(D:/foobar/sunGui.jar:0)
   at 
java.lang.Class.initializeClass(/foobar/GCC-source/libjava/java/lang/natClass.cc:750)
   at 
java.lang.Class.initializeClass(/foobar/GCC-source/libjava/java/lang/Class.h:651)
   at 
java.lang.Class.initializeClass(/foobar/GCC-source/libjava/java/lang/Class.h:651)
   at 
java.lang.Class.initializeClass(/foobar/GCC-source/libjava/java/lang/Class.h:651)


It looks like:
1. java.awt.Component is initialized
2. it calls initIDs which is a JNI method
3. initIDs tries to load WComponentPeer (which is in the binary) but 
runs in a JV_STATE_ERROR in natClass.cc:719

I have no idea where to start with this. Can this be a problem of native 
compilation (initializeClass called while in initializeClass)? Maybe a 
problem with JNI? Am I missing some basic knowledge?

I have to mention that I'm trying this on mingw, not on Linux. GCJ 
compiled binaries for Linux seem to have problems with stacktraces 
during initialization for quite a while now. When an exception occur and 
the binary is stripped, something like <<No Stacktrace available>> 
appears. If the binary is created with debug data, it just prints "Aborted".

Hints? Ideas?


thanks
