The NegativeArraySizeException occurs only sometimes, in particular it doesn't
seem to appear when I start the program under gdb. If it hangs and I interrupt
it, I get this stack trace:

[...]
lock: ../../../libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GdkGraphics.c, 146
unlock: ../../../libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GdkGraphics.c, 158

Program received signal SIGINT, Interrupt.
