[xep-support] JIT Compiler "off" not found

Chris,

The only error I see is that strictly speaking "-Xmx400mb" should be "-Xmx400m",
but I fail to see how that could affect JIT settings. The only way I know in JDK1.3
to turn of the JIT is with the option -Xint. By default the client HotSpot JIT is
active.

All this is of course about the Sun JRE. I think you use the one from IBM. Could you
therefore send the usage string of the java command?

Werner.
