runtime performance statistics in java.util.concurrent


Are there are runtime performance statistics available within java.util.concurrent? I've looked through the code and documentation, but only found limited stats enabled by COLLECT_STATS for FJTaskRunner.

I am looking for normal queueing level statistics that would tell me the average queue length, service time, and wait time over a sample period.

How do people investigate potential runtime problems where using these methods could cause locking and syncronization problems? Please advise.
