      Description

      A DESCRIPTION OF THE PROBLEM :
      ThreadGroup.enumerate() sometimes returns a small value (eg. 1) when in fact there are many threads in the system. The problem is caused because the method

      private int enumerate(Thread list[], int n, boolean recurse)

      Sometimes returns 0 , when it should return n

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      No steps. I think the description is clear


      FREQUENCY : occasionally
