Java dumps core with eclipse after recent upgrade

Hi

After usual upgrade of world and some ports java dumps core when started
by eclipse:

% eclipse
Fatal error 'thr_resume_wrapper, lock_switch != 0
' at line 1119 in file /usr/src/lib/libpthread/thread/thr_kern.c (errno
= 174487
7412)

... (many times) ...

It shows:

% ls -l *core

stack-trace is useless for my taste - infinite list of empty frames:
% gdb /usr/local/jdk1.5.0/bin/java java.core 
...
Core was generated by `java'.

Force upgrade of eclipse does not helps.

jdk15 is not latest (latest does not build) and was not changed during
this upgrade.

Booting with old kernel does not helps also.

% pkg_info -I jdk\* eclipse\*

particul

Any hints will be very appreciated.
