Plexus.sh doesn't run on a Aix JVM

I'm upgrading to continuum 1.1. We were using continuum 1.0.3 until now.

As there's no wrapper for this platform, we directly start the plexus.sh script.
Since the 1.1, the "-XX:MaxPermSize" option has been added.

Unfortunalely, it seems like it's an option that's only supported by HotSpot (or at least, not by the IBM JVM on Aix).
Here the error :
[P520]/cic/soft/continuum-1.1/bin:./plexus.sh.original
Using PLEXUS_HOME: /cic/soft/continuum-1.1
Using PLEXUS_BASE: /cic/soft/continuum-1.1
Using PLEXUS_TMPDIR: /cic/soft/continuum-1.1/temp
Using JAVA_HOME: /cic/soft/java
JVMJ9VM007E Command-line option unrecognised: -XX:MaxPermSize=128m
Could not create JVM.
Usage: java [-options] class [args...]

So I wrote a small patch to activate this option only when java -version contains "HotSpot".

I'm attaching the diff between the plexus.sh included in the 1.1 distribution and the one I modified + the modified one for convenience.

There was also a small problem at the beginning on the file :
PLEXUS_OPTS="$PLEXUS_OPTS -Xmx384" without the m.

On my conf, this displays :
[P520]/cic/soft/continuum-1.1/bin:./plexus.sh

JVMJ9GC017E -Xmx too small, must be at least 1 Mbytes

Please feel free to ask any question or do any modification you want on this patch.

Cheers.
