Hi,

Probably, you missed a step, or did something wrong while executing the java upgrade.
Review that note and ensure you have all the required things properly.. If you are sure about that,  check the log.. oacore log will tell you what the issue is.. Currently, your oacore is acore_server1 is FAILED_NOT_RESTARTABLE mode, so there must be something crucial there.
