The regression test (testbase_nsk) nsk/regression/b4298656 crashes
the HotSpot Server VM (2.0, build A) on Solaris.

The test calls recursive_method() in loop.
The second stack overflow crashes HotSpot Server VM.

To reproduce the bug run doit.sh in
/net/sqesvr/vsn/GammaBase/Bugs/<this bug number>.

The first parameter for doit.sh should be JDK root directory
(e.g. /usr/local/java/jdk1.2.2/solaris) and the second parameter -
VM option(s) (optional).

The doit.sh file contains the CALL_DEPTH variable which is
the number of recursive calls.
By default the CALL_DEPTH variable equals 1000000.

The Kestrel HotSpot VM (build 1.3-R) runs the test perfectly.
