Hi Chris,

changes look good, the only note, seems like formatting moved a bit
-                "-Xss" + stackSize + "000", "-XshowSettings", "-jar", testJar.getAbsolutePath());
+                    "-Xss" + (stackSize * 1024), "-XshowSettings", "-jar", testJar.getAbsolutePath());

Best regards,
Stanislav Smirnov

> 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.
