* @test
*
* @summary converted from VM Testbase nsk/monitoring/ThreadMXBean/resetPeakThreadCount/reset001..reset005
* VM Testbase keywords: [quick, monitoring]
* VM Testbase readme:
* DESCRIPTION
* The test checks that
* ThreadMXBean.resetPeakThreadCount()
* returns correct result.
* The test starts a couple of user threads and waits until they finish. After
* that, resetPeakThreadCount() is invoked to reset the peak. Then
* getPeakThreadCount() and getThreadCount() must return the same values. The
* expectation is that no threads are created, or terminated, between
* "getPeakThreadCount()" and getThreadCount()" calls.
* The test implements defferent ways to access to the metrics.
*
* @comment Direct access to the metrics.
* @library /vmTestbase
* /test/lib
* @run main/othervm nsk.monitoring.ThreadMXBean.resetPeakThreadCount.reset001
