Be able to run GLU on IBM's JDK.

[lbruand]

Hello,

First of all, thanks for opensourcing GLU. This is great software!!!
I would like to start working specifically on removing the requirement to run GLU on Oracle's JDK exclusively (as noted #74 ) and allow using IBM's jdk.
I post this issue so people know. I will try publish a patch when I have something decent.

Cheers,
Lucas Bruand

Hi Lucas

Thank you for posting this update and good luck. To be honest with you it may just work with IBM's jdk. glu has been developed and heavily tested with Oracle JVM and it has been proven to not work with OpenJDK. So it was just easier to say that it works only with Oracle JDK. I hope you can simply make it work with IBM's :)

Thanks
Yan

First issue :
Agent-jvm not started because -Xloggc: parameter is not supported by IBM's jdk...

Thanks Yan !

Hi Yan,

Just dropping a few lines to say we have successfully ported GLU to AIX/IBM JDK.

Thanks,
Lucas

That is really cool. Can you share the changes?

This issue, also a recompilation of SIGAR, that's it ! :-)
