Hi vidyadhards,
Its not supported Java 8.0 in WebSphere 8.0.
WebSphere 8.0 Java 6 (J9 2.6)
www-969.ibm.com/software/reports/compati... In my opinion I don't think that IBM will support Java 8, because now is not supporting Java 7 in WAS v8...but who knows maybe in fixpack 8.0.0.11 or 8.0.0.XX
Hope this helps. Tell us if you need more support
regards
