Splunk Add-on for Java Management Extensions 3.1.1: Why am I getting error "Unable to initialize modular input "jmx""?

Installed the Splunk Add-on for Java Management Extensions 3.1.1, and after restarting, I'm getting the error:

Unable to initialize modular input "jmx"

People have mentioned that the path to Java might be an issue, but I'm running Splunk DB Connect 2 on the same machine, using the following:

 echo $JAVA_HOME
/home/splunkforwarder/jdk1.8.0_65/bin/java

and it's running fine. Do I need to define something that the instructions don't list?

Change $JAVA_HOME to

/home/splunkforwarder/jdk1.8.0_65

Hi banderson7,

Most runtime errors will be written to $SPLUNK_HOME/var/log/splunk/jmx.log. Some errors can be found in $SPLUNK_HOME/var/log/splunk/splunkd.log. Does anything interesting show up there?

Also, please note that the Splunk Add-on for Java Management Extensions supports the following JMX Connectors:

rmi (JSR160 Standard Implementation
and MX4J's JSR160 Implementation)
iiop (JSR160 Standard Implementation
and MX4J's JSR160 Implementation)
soap (MX4J only) hessian (MX4J only)
burlap (MX4J only)

Note: If you are using Java 8, MX4J protocols are not supported.

This is what shows in splunkd.log, jmx.log doesn't exist in $SPLUNK_HOME/var/log/splunk/...
