Resolution
To resolve this, the built-in JRE needs to be upgraded.Resolution 1:Upgrade the FMS to 5.7.5.6 or above, which should comes with a newer version of JRE.
Resolution 2:
If an FMS upgrade is not possible, upgrade the JRE manually by following the steps below.- Stop the FMS
- Go to the Oracle webpage
- Download the file "u8101 JRE tar.gz"
- Rename $FMS_HOME\jre to $FMS_HOME\jre.old
- Decompress the file $FMS_HOME\jre. Make sure it has the same directory structure as before.
- Start the FMS
