tests/threads/threadInterrupt.java

   1 // This test has been added because of a bug in CACAO that allowed threads
   2 // blocked inside monitorenter to be interrupted. In the presence of the bug,
   3 // the program would not exit.
   4 //
   5 // The bug has been fixed as part of the sable lock implementation.
