Incorrect statistcs returned by the EJB MBean in EAP 5.1

1) Deploy the etat.ear 2) Start up the EAP server 3) Setup some vars for use by twiddle commands: serverUrl='jnp://localhost:1099' jmxUser='admin' jmxPassword='admin' mBeanName='jboss.j2ee:jndiName=TestBean,service=EJB' mBeanAttr='DetypedInvocationStatistics' mBeanOperation='resetInvocationStats' 4) Run twiddle to make sure it is working and given a base-line: ./twiddle.sh -s "${serverUrl}" -u "${jmxUser}" -p "${jmxPassword}" get "${mBeanName}" "${mBeanAttr}" Should see something similar to: DetypedInvocationStatistics={#Global={lastResetTime=1304634714452, concurrentCalls=0, maxConcurrentCalls=0}} 5) Now invoke the EJB using the servlet: wget "http://localhost:8080/etatWeb/TestEJBServlet" -a etat.log 6) Run twiddle again to see that it actually invoked the EJB and we have valid stats: ./twiddle.sh -s "${serverUrl}" -u "${jmxUser}" -p "${jmxPassword}" get "${mBeanName}" "${mBeanAttr}" Should look something like: DetypedInvocationStatistics={remove= {minTime=1, maxTime=1, count=1, totalTime=1} , create= {minTime=121, maxTime=121, count=1, totalTime=121} , sayHello= {minTime=3, maxTime=3, count=1, totalTime=3} , #Global={lastResetTime=1304635345747, concurrentCalls=0, maxConcurrentCalls=1}} 7) And here is how we make things go bad, invoke the resetInvocationStats operation on the EJB using twiddle: ./twiddle.sh -s "${serverUrl}" -u "${jmxUser}" -p "${jmxPassword}" invoke "${mBeanName}" "${mBeanOperation}" 8) The resetInvocationStats operation will be successful but look what happens when we get the stats now: ./twiddle.sh -s "${serverUrl}" -u "${jmxUser}" -p "${jmxPassword}" get "${mBeanName}" "${mBeanAttr}" You should get some wacky results similar to: DetypedInvocationStatistics={remove= {minTime=9223372036854775807, maxTime=0, count=0, totalTime=0}, create={minTime=9223372036854775807, maxTime=0, count=0, totalTime=0} , sayHello= {minTime=9223372036854775807, maxTime=0, count=0, totalTime=0} , #Global={lastResetTime=1304635363064, concurrentCalls=0, maxConcurrentCalls=0}} So, looking at what we get, it is the minTime that is wrong. we should expect it to be 0. This is probably happening because after a reset we should probably expected the stats to look like: DetypedInvocationStatistics={#Global= {lastResetTime=1304634714452, concurrentCalls=0, maxConcurrentCalls=0} }

EJB method invocation statistics returned by the InvocationStatistics MBean would include a value of <Long.MAX_VALUE> for minimum execution time (minTime) after a call to resetStats. The fix is to clear the method invocation statistics list after the resetStats call so that the stats reflect the same state they did when the EJB was first initialized.
