Kestrel HotSpot Client build + Solaris_JDK_1.3-b09 fails the test
nsk/regression/b4254544 from testbase_nsk when either -Xcomp or -Xmixed option
is passed in.

The test inserts HashMap into itself which crashes VM.

VM behaves differently for different options:
-Xmixed : Segmentation Fault (intermittently)
-Xcomp : An irrecoverable stack overflow has occurred.
          Unexpected Signal 11
-Xint : pass

Crash in -Xmixed mode is intermittent. I managed to reproduce it twice of 10 runs on
Ultra-1, single CPU, 266 MHz, 128M RAM, SunOS 5.7.

See also similar bug #4326445 filed against Server VM which was fixed/integrated
on 04/03/2000.

To reproduce the bug run multiple times:
doit.sh <jdk root directory> -Xmixed
or
doit.sh <jdk root directory> -Xcomp
in
/net/sqesvr/vsn/GammaBase/Bugs/<this bug number>

The test produces the output:
