      1) Log in to jmx-console and follow the "type=Server" link under the jboss.system section
      2) Invoke runGarbageCollector method
      3) Verify in gc logging that no GC took place

    • Hide
      The traceInstructions, traceMethodCalls, runGarbageCollector and runFinalization methods in org.jboss.system.server.jmx.JMXKernel were empty. Calling these methods was therefore successful, but no operation was actually performed by them. The code of the methods has been extended to call the alike named methods in java.lang.Runtime. The methods are now no longer empty and the expected operations are performed when the methods are called.

      Following the "type=Server" link under the jboss.system section of the jmx-console, there are several methods that appear to do nothing (traceInstructions, traceMethodCalls, runGarbageCollector, runFinalization). Invoking them returns the result on the page "Operation completed successfully without a return value!" But nothing is done. It looks like the issue is several empty methods in org.jboss.system.server.jmx.JMXKernel. These worked in EAP 4.3, which relied on org.jboss.system.server.ServerImpl for this functionality. Looks like functionality was not fully ported over to the new JMXKernel class that took its place.
