Hello,
I'm getting following warning with 6.0.29,
after shutdown:
SEVERE: The web application [/moskitodemo] appears to have started a
thread named [MoskitoMemoryPoolReader] but has failed to stop it. This
is very likely to create a memory leak.
here's the snapshot of the code that starts the thread:
public class BuiltInMemoryPoolProducer implements IStatsProducer{
/**
* Timer instance for this producer type.
*/
private static final Timer timer = new Timer("MoskitoMemoryPoolReader",
true);
...
public BuiltInMemoryPoolProducer(MemoryPoolMXBean aPool){
timer.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
readMemory();
}
}, 0, 1000L*60);
...}
to my knowledge this thread is a daemon. This knowledge is also shared
by jstack:
"MoskitoMemoryPoolReader" daemon prio=5 tid=10883f800 nid=0x11a9b2000
in Object.wait() [11a9b1000]
java.lang.Thread.State: TIMED_WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
- waiting on <10a1120d0> (a java.util.TaskQueue)
at java.util.TimerThread.mainLoop(Timer.java:509)
- locked <10a1120d0> (a java.util.TaskQueue)
at java.util.TimerThread.run(Timer.java:462)
So, how can I avoid this warning and where's the bug.
regards
Leon
