Ok, I am giving up on it...
Using JDK1.2 prev1 and v2, we ran in a strange problem.
Everytime an applet or application is started, whenever some awt stuff is used,
the whole JRE segfaults like this:
SIGSEGV 11* segmentation violation
stackpointer=0x417b3c98
Full thread dump Classic VM (Linux_JDK_1.2_pre-release-v2, green threads):
"Screen Updater" (TID:0x404d9550, sys_thread_t:0x84cba88, state:CW) prio=4
at java.lang.Object.wait(Native Method)
at java.lang.Object.wait(Object.java:424)
at sun.awt.ScreenUpdater.nextEntry(ScreenUpdater.java:79)
at sun.awt.ScreenUpdater.run(ScreenUpdater.java:99)
Before this happens, Motif gives out a warning about
Warning:
Name: HorScrollBar
Class: XmScrollBar
The specified scrollbar value is greater than the maximum
scrollbar value minus the scrollbar slider size.
and text drawn by DrawString is broken into strange pixels, going through
several bitplanes.
Because of this, I believe it must be Motif related.
Installing Motif 1.2.4, 2.0 and Lesstif did not change anything.
The systems are SuSE 6.0 and 6.1 (kernel 2.2.5) with glibc2.0 which does not
seem to be important to reproduce the problem.
The strangest thing: We have one machine (SuSE 6.1) on which it all works.
It is definitely related to the machine and its installation, as we did several
cross login tests to and from other machines.
Attached is the full thread dump, just in case someone likes it or has an idea.
Thanks for any hint.
Oliver
