The Hotspot VM both build 1.3.0-B and build 1.3-b12 for Solaris
(both java and java_g) intermittently fails the test
        nsk/jvmpi/events/mncntenter001
from
        testbase_nsk

To reproduce the bug run Korn shell script
        doit.ksh <jdk_root_directory>
in
        /net/sqesvr/vsn/GammaBase/Bugs/<this bug number>

The script produces the output:
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-B)
Java HotSpot(TM) Client VM (build 1.3.0-B, interpreted mode)
