Has anyone used IBM JRE6 with WR9.2 & WR Java Add-in7.6 ?

I have been using Sun JRE6 with WR9.2 on XP, for that I had to use patches for Add-in.
But I don't think any patches are available for IBM JRE.

If any one has used IBM JRE(any version) with WR then kindly do provide inputs about how it differs from Sun JRE.

Please do help me in this regard.
