Please review the following:
After fixing 8175342 (see the other RFR I just posted), this test
started to fail instead of assert. The problem is 256000 is too small of
a stack size on the platform in question. It needs to be at least 256k.
The test has a "stackSize" local variable that is the String "256". It
runs the jvm with -Xss of this size, appending "k" to it on one run and
"000" in the next. The -Xss256k version is fine. The -Xss256000 version
is not. I'm not sure why the test chose to specify the stackSize as a
String instead of an int. As part of this fix I changed it to an int,
and just multiply it by 1024 in the case where -Xss is specified with a
byte size rather the an k size. The test passes now on the platform
where it was failing.
