The base 8.3 had JRockit JDK as well as Sun JDK as a tested configuration.
Later 8.3 SP1 only has Sun JDK as a tested configuration.
Can anyone comment on this. If I decide to deploy 8.3 SP1 with the latest hotfix available should I just use the tested Sun JDK for the app server?
JRockit JDK is supported with P6 EPPM 8.3 SP1 and any latest hotfix. The tested configuration for SP1 and above is an indication that additional certification of latest JDK has been done. It does not necessarily mean you need to upgrade to it although recommended. Review the SP1 patch readme for more information.
