751 * Bug in IBM JVM 1.6. For some reason, under
752 * conditions that are yet to be full understood,
753 * Thread.currentThread() is either returning null
754 * or a different instance from the one that was
755 * saved when the Display was created. This is
756 * possibly a JIT problem because modifying this
757 * method to print logging information when the
758 * error happens seems to fix the problem. The
759 * fix is to use operating system calls to verify
760 * that the current thread is not the Display thread.
761 *
762 * NOTE: Despite the fact that Thread.currentThread()
763 * is used in other places, the failure has not been
764 * observed in all places where it is called.
