Running frysk on a 64 bit host results in 26-Jan-06 1:25:57 PM frysk.gui.FryskGui importPreferences WARNING: /home/cygnus/dnovillo/.frysk/.settings not found. Will be created on program exit Exception in thread "main" java.lang.NullPointerException at java.lang.Object.getClass (libgcj.so.7) at org.gnu.gtk.frysk.EggTrayIcon.egg_tray_icon_new (EggTrayIcon.java:72) at org.gnu.gtk.frysk.EggTrayIcon.<init> (EggTrayIcon.java:52) at frysk.gui.monitor.TrayIcon.<init> (TrayIcon.java:97) at frysk.gui.FryskGui.mainGui (FryskGui.java:174) at frysk.gui.FryskGui.main (FryskGui.java:259) The problem seems to be a dereference of a sign-extended pointer in #1 0x00002aaaad740686 in unwrap<java::lang::Object> (obj=0xffffffffb305f990) at ../../../libjava/jni.cc:223 223 if (obj == NULL || obj->getClass () != &JNIWeakRef::class$) Pointer 'obj' is invalid. The previous time this came up (http://sourceware.org/bugzilla/show_bug.cgi?id=2213), a C function returning pointers was being compiled without proper prototypes. 2006-01-26 Andrew Cagney <cagney@redhat.com> * libEggTrayIcon.c: Include "eggtrayicon.h", and <gtk_java.h>. Cast EggTrayIcon object to GObject. |
