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
