[FRS-464] Issue running FusionReactor with OpenJDK 11.0.2 – 11.0.4

Due to a bug introduced in Java 11.0.2, some customers are seeing random crashes of their server with FusionReactor installed.

The bug in Java is an issue with the JIT compiler, it appears a somewhat random function in Java will fail to compile when an attempt to optimize the function is made. When this happens an exception occurs that terminates the JVM, taking down the application server.

When this issue occurs you will see a Java PID error file similar too:

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

#

# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00007ffa4d823808, pid=5556, tid=4372

This issue has been resolved in OpenJDK version 11.0.5.

At this time this version of OpenJDK is not available for download, so if you are experiencing this issue we recommend downgrading the JRE used on your application server to avoid hitting this issue.
