1 <p> A call to <code>notify()</code> or <code>notifyAll()</code>
2 was made without any (apparent) accompanying
3 modification to mutable object state. In general, calling a notify
4 method on a monitor is done because some condition another thread is
5 waiting for has become true. However, for the condition to be meaningful,
6 it must involve a heap object that is visible to both threads.</p>
8 <p> This bug does not necessarily indicate an error, since the change to
9 mutable object state may have taken place in a method which then called
10 the method containing the notification.</p>
