Java线程监视\\\\分析\\\\测量

我熟悉
http://download.oracle.com/javase/6/docs/api/java/lang/management/ThreadMXBean.html
我想测试\\ profile \\测量线程获得多少CPU时间。
我在我的线程构造函数中添加了以下内容：
ManagementFactory.getThreadMXBean().setThreadCpuTimeEnabled(true);
if(!ManagementFactory.getThreadMXBean().isCurrentThreadCpuTimeSupported())
System.err.println(\"measure is not supported.\");
ManagementFactory.getThreadMXBean().setThreadContentionMonitoringEnabled(true);
if(!ManagementFactory.getThreadMXBean().isCurrentThreadCpuTimeSupported())
System.err.println(\"contention is not supported.\");
long tID = Thread.currentThread().getId();
long execTime = ManagementFactory.getThreadMXBean().getThreadCpuTime(tID);
