Apply the steps mentioned at the following link from Oracle to run the FPUpdater tool that patches the concerned rt.jar and resolves the security vulnerability.

The JRE instance to be patched is installed under $ESEC_HOME/jre<64> for various Sentinel platforms. This workaround is applicable for remote collector manager service as well. After the FPUpdater tool has run once, it is a good idea to run it again in order to verify that the patch has been correctly installed.

Make sure to stop all Sentinel processes before executing the fpupdater tool and restart them afterwards.
