why is "gdb /home/gat/JAVA/JDK16/jdk1.6.0/bin/java" so broken?

["U. George" <gatgul@gatworks.com>]

After some 60min of running javasoft's java, the program finally dies of 
a segfault. I have been trying, and apparently for several years now, 
according to the gdb bug base, to get GDB to work with java & threads.
Version 6.4 does not work any better.
there is something wrong in libthread_db.so. I'm not yet willing to just 
replace the libs, as this may affect the 'heap' bug that shows itself 
randomly.

So whats goin on with gdb?
