The Thread.sleep method throws an
IllegalMonitorStateException during Y2K testing when the system date is set
to 1/1/2038.Cust says that the Java Bug Report bug ID 4143186 lists this as a problem with Solaris for arguments larger than Integer.MAX_VALUE, but does not sayanything about dates in the future causing the same problem.
The argument that cust. passes to sleep is 500, so the argument should not be
causingthe problem. The call works with the
year set to 2004.



Here is the testcase:


public class TestSleep {

   public static void main( String args[] ) {
      (new TestThread()).start();
   }
}

class TestThread extends Thread {
   public void run() {
      while (true) {
         System.out.println( "Sleeping" );
         try {
            this.sleep( 500L );
         }
         catch( Exception e ) {
            System.out.println( "Sleep received exception : " + e );
         }
      }
   }
}
