Title:
  gnu_java_awt_peer_gtk_GtkImage.c fails with a simple test case

Status in The GNU Compiler Collection:
  Invalid
Status in “gcc-defaults” package in Ubuntu:
  Fix Released

Bug description:
  I have filed this bug as http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26152
  in the GCJ bug tracker.
  Maybe in newer gcj versions this problem is solved. Is there any possibility to get newer packages, such as 4.0.2 instead of 4.0 ? I have little clue on how to go about compiling them myself, since the GCC site is such a mess and provides only the information I don't need for the purpose, or I have failed to find it.

  A copy of the bug report:

  
  ImageJ, the public domain scientific-grade image processing application
  compiles fine with the gcj-wrapper-4.0 in Kubuntu GNU/Linux-ppc when stripped
  of JPEG functionality and its dependance on the tools.jar. But when trying to
  open an image, the gtkImage.c file complains:

  ** ERROR **: file
  ../../../src/libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkImage.c: line 572
  (createRawData): assertion failed: (data_fid != 0)
  aborting...

  
  I attach a self-contained test case below. Here are the commands to compile and
  run it:

  $ /usr/bin/gcj-wrapper-4.0 -g testGtkImage.java
  $ /usr/lib/jvm/java-gcj/bin/java testGtkImage

  
  The JFileChooser never shows. Here's the error message:

  
  ** ERROR **: file
  ../../../src/libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkImage.c: line 572
  (createRawData): assertion failed: (data_fid != 0)
  aborting...
  Aborted
