Confluence crashes due to 'Internal Error (sharedRuntime.cpp:833)' caused by Java 8 bug
Problem
Confluence Crashes with JRE error and the JVM generates a hs_err_pid
file with entries similar to the one below:
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (sharedRuntime.cpp:833), pid=28631, tid=139690008549120

Cause
This happens due to a bug in OpenJDK (JDK-8067755) and is triggered by terminating SSL at Tomcat/Confluence.
Supposedly the issue is fixed now, but Java 8u25 and Java 8u40 are both affected (details on the issue above). Java 8u45 has been released but the problem will most likely persist.
Workaround
- Add the
-XX:-UseAESIntrinsics
flag to the JVM.Linux
Windows Service
The flag provided above should work however, the original Tomcat thread suggests adding the parameter below instead:
-XX:CompileCommand=exclude,com/sun/crypto/provider/\*.\*
We've had customers succeed by adding the UseAESIntrinsics
parameter so only use this option if that one doesn't work.
Resolution
- Upgrade Java to Java 8u60 or above.
