The description for the methods ThreadMBean.getThreadCpuTime(long id) says:
"Throws: java.lang.IllegalArgumentException - if id <= 0"
But jdk1.5.0-b16 does not throw the IllegalArgumentException for invalid id.

Source code:
=========================== a.java ====================================
import java.lang.management.*;
import java.io.PrintStream;

class a {
    
    void test() {

        ThreadMBean c = ManagementFactory.getThreadMBean();
        int cnt = 0;
        long [] idArr = {0, -1, -2, (Long.MIN_VALUE + 1), Long.MIN_VALUE};
 
        try {
            for (int i = 0; i < idArr.length; i++) {
                try {
                    c.getThreadCpuTime(idArr[i]);
                    System.out.println("Test failed. IllegalArgumentException expected for
ID = " + idArr[i]);
                } catch (IllegalArgumentException iae) {
                    cnt++;
                }
            }
        } catch (UnsupportedOperationException ue) {
        }
        System.out.println("OKAY");
    }

    public static void main(String argv[]) {
        new a().test();
    }
}
