imageJ crashing

[Albert Cardona <cardona at ucla dot edu>]

hi all,

I've finally managed to get a gcj 4.1 running. Now that the gtk_Image bug is 
fixed, I'm running into new bugs. The menus have a black background, but not 
the menubar, and thus text menu items are only visible when the mouse is over 
them, while the terminal keeps complaining about:

(.:10951): Gdk-WARNING **: gdk_window_set_back_pixmap(): pixmap must have a 
colormap
java.lang.InternalError: Gdk: gdk_window_set_back_pixmap(): pixmap must have a 
colormap
at java.lang.reflect.Constructor.newInstance(libgcj.so.7)

Then, when opening a new image, the GenericDialog (extends java.awt.Dialog) 
opens just fine, with black background as well, and then at the creation of a 
new image the application crashes:

10951 Aborted                 /usr/lib/jvm/java-gcj/bin/java -jar ij.jar


The application ImageJ 1.37g ( http://rsb.info.nih.gov/ij ) I want to run has 
been compiled with gcj (once stripped off tools.jar and jpeg requirements, 
changes in about 20 lines at most).

I compiled it with the '-g' flag and tried to run the GDB on it. It behaves 
just the same and the GDB claims there is no backtrace. I suspect then the 
problem is in the core JVM, which I installed from the ubuntu repositories.

My machine:
PowerBook Ti 3.5 1GHz, running Kubuntu-ppc 6.06

Any help or hints appreciated. I tried to obtain a JVM compiled with '-g' but 
to no avail, I would appreciate instructions on how to do it.

The application is only 1 MB and widely used in the scientific comunity. It 
would be very nice to have this public domain tool running natively and 
independently of any java virtual machine. I can provide the edited source 
code and compiling scripts on demand.

Thanks for any help.

Albert
