FMS server crashes unexpectedly. Crash dump shows SIGSEGV fault. (4294070)

FMS server running on Red Hat Enterprise Linux 7.x crashes unexpectedly. Crash dumps in main FMS directory hs_err_pidNNN.log shows a SIGSEGV fault. 

# A fatal error has been detected by the Java Runtime Environment:

This seems to be an issue that affects OpenJDK 1.8.0_212 (25.212-b04) and 1.8.0_222 (25.222-b10) on Linux, these are the OpenJDK versions shipped with Foglight 5.9.5 and 5.9.7 respectively.

The suspected associated defect in OpenJDK is ZULU-5050 (Memory leak in crypto provider verification introduced in October 2019 PSU release).

Upgrade the JRE to OpenJDK 1.8.0_252 (25.252−b14)

1. Make a backup of the current JRE directory of the FMS.  [FMS_HOME]/jre
2. Download the latest JRE from https://www.azul.com/downloads/zulu-community/?version=java-8-lts&os=rhel&architecture=x86-64-bit&package=jre. Make sure to select the .tar.gz option. The file tested in the lab was zulu8.46.0.19-ca-jre8.0.252-linux_x64.tar.gz
3. Extract the tarball to any directory of your choice. E.g tar -xzvf zulu8.46.0.19-ca-jre8.0.252-linux_x64.tar.gz -C /mydirectory
4. Shut down the FMS and delete or rename the [FMS_HOME]/jre directory.
5. Go to the directory in step 3, there should be a new directory named after the file downloaded in step 2. E.g. zulu8.46.0.19-ca-jre8.0.252-linux_x64
6. Move this new directory to the Foglight jre directory, e.g mv zulu8.46.0.19-ca-jre8.0.252-linux_x64 [FMS_HOME]/jre
7. Restart the FMS and verify that it starts correctly.

Logged as FGL-20570 to include new OpenJDK on future release.
