EVALUATION The actual problem is that the quit() method lacks gtk synchronization. It calls gtk_widget_hide() etc., but doesn't invoke gdk_threads_enter() prior to that. If the synchronization is in place, the JVM doesn't crash, and the test passes.

EVALUATION Some observations: 1. The getLocationOnScreen() method of the gtk file dialog returns the (0, 0) point of the main screen. It should probably retrieve the location from gtk instead. 2. The GtkFileDialogPeer and its native counter-part consider that the FileDialog is kind of a singletone. E.g. there's static GtkWidget *dialog = NULL; in the src/solaris/native/sun/awt/sun_awt_X11_GtkFileDialogPeer.c. 3. If the dialog is disposed prior to exiting from the test, the test doesn't crash. 4. If I turn the test to a main test (i.e. @run main ..., and add a corresponding main() mathod that would do new FileDialogBufferOverflowTest().start();) the test always passes. So this may be related to the appletviewer/jtreg machinery somehow.

EVALUATION The test sometimes passes, sometimes showing the dialog in a very weird size/location. Sometimes it crashes with a stack different from the initally reported one: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0xa70655b4, pid=26336, tid=2769611664 # # JRE version: 7.0 # Java VM: Java HotSpot(TM) Server VM (17.0-b03 mixed mode linux-x86 ) # Problematic frame: # C [libatk-1.0.so.0+0xc5b4] atk_registry_get_factory_type+0x24 # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. # Stack: [0xa50fe000,0xa514f000], sp=0xa514d6c0, free space=13da514d064k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libatk-1.0.so.0+0xc5b4] atk_registry_get_factory_type+0x24 [error occurred during error reporting (printing native stack), id 0xb] Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) j sun.awt.X11.GtkFileDialogPeer.run(Ljava/lang/String;ILjava/lang/String;Ljava/lang/String;Ljava/io/FilenameFilter;Z)V+0 j sun.awt.X11.GtkFileDialogPeer.access$100(Lsun/awt/X11/GtkFileDialogPeer;Ljava/lang/String;ILjava/lang/String;Ljava/lang/String;Ljava/io/FilenameFilter;Z)V+10 j sun.awt.X11.GtkFileDialogPeer$1.run()V+64 v ~StubRoutines::call_stub #20 <signal handler called> No symbol table info available. #21 0xa70655b4 in atk_registry_get_factory_type () from /usr/lib/libatk-1.0.so.0 No symbol table info available. #22 0xa7065612 in atk_registry_get_factory () from /usr/lib/libatk-1.0.so.0 No symbol table info available. #23 0xa7362a4d in ??
