[Bug classpath/22835] jamvm crash with Swing

[gcc-bugzilla at gcc dot gnu dot org]

Recent gtk-peer changes broke swing:

classpath cvs / jamvm 1.2.3 + fixes from jamvm list
GTK 2.4.14-2 from Debian
-----------------------
import javax.swing.JFrame;
public class Swing {
    public static void main(String [] args) {
        JFrame f = new JFrame();
        f.show();
    }
}

jamvm 1.2.3 does not work anymore. The new GTK peer mege just triggered a bug
in jamvm 1.2.3. You need this patch:

--- jamvm-1.2.3/src/dll.c       2004-12-23 12:11:32.000000000 +0100
+++ jamvm-1.2.3.patched/src/dll.c       2005-01-10 23:05:22.000000000 +0100
@@ -290,8 +290,8 @@
     return NULL;
 }

+static void *env = &Jam_JNINativeInterface;
 u4 *callJNIWrapper(Class *class, MethodBlock *mb, u4 *ostack) {
-    void *env = &Jam_JNINativeInterface;

     TRACE(("<DLL: Calling JNI method %s.%s%s>\n", CLASS_CB(class)->name,
mb->name, mb->type));

I eave this bug open until new jamvm gets released which fixes the issue.

Thanks, now it works again!

Btw, the ToolTipManager bug still exists.

Do you have these patches applied too ? With them I cant reproduce it anymore.

Ah, the first one in your list was missing.

Applied, but no effect - still got the exception.

Attached patch with all jamvm changes I have.

Could this be tested again with current JamVM and Classpath 0.14? I don't see
any problems here, though I use a newer GTK so I can't be sure. If there are no
problems anymore, I would close this bug.


------- Comment #6 from from-classpath at savannah dot gnu dot org  2005-04-22

This bug can indeed be closed.

As for #11538, I need to re-test.

Reported fixed.
Thanks Marko.
