[Bug AWT/17254] New: [java-gui-branch] Hang when resizing AWT window on Alpha

["falk at debian dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

If I start the libjava/gnu/java/awt/peer/gtk/TestAWT.java program:

gcj -v TestAWT.java --main=TestAWT && ./a.out

I get a nice window. If I then resize it quickly with a window manager with
"solid resize", the program hangs and doesn't do any redraws any more.

I'll attach the output of the program when DEBUG_LOCKING is enabled.
