[Bug libgcj/23216] New: IncompatibleClassChangeError when Using Java-Gnome

[ajocksch at redhat dot com]

When running a simple Java-Gnome app, I get a IncompatibleClassChangeError. The 
following test case produces the bug. I've tested this with the IBM and BEA 
jvms as well and both of these work fine, so I don't suspect that Java-Gnome is 
to blame. 
 
----------------------- 
import org.gnu.gtk.Gtk; 
import org.gnu.gtk.TextView; 
 
public class TestCase { 
 
	/** 
	 * @param args 
	 */ 
	public static void main(String[] args) { 
		System.out.println("before initializing GTK"); 
		Gtk.init(args); 
		System.out.println("after initializing GTK\nBefore initializing 
TextView"); 
		TextView tv = new TextView(); 
		System.out.println("after initializing TextView\nBefore getting 
buffer 1st time"); 
		tv.getBuffer(); 
		System.out.println("after getting buffer 1st time\nBefore 
getting buffer 2nd time"); 
		tv.getBuffer(); 
		System.out.println("after getting buffer 2nd time"); 
	} 
 
}

I tried this with the gcc 4.0 and java-gnome that ship on Fedora Core 4.
It worked for me.

Can you give some more information?  Perhaps the stack trace that you see?
Did you compile this or run it interpreted?

Sorry, I should have clarified earlier that I'm developing with Java-Gnome head.
I am running it interpreted through Eclipse.

Here's the stack trace it generates:
Exception in thread "main" java.lang.IncompatibleClassChangeError

No testcase, ancient Java (and now gnome) version.
