FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
at last of method initBean(Class type, Object oldInstance, Object newInstance, Encoder out):
line 316:
String removeListenerMethodName = d.getRemoveListenerMethod().getName();
            for (int i = oldL.length; i < newL.length; i++) {
                invokeStatement(oldInstance, removeListenerMethodName, new Object[]{oldL[i]}, out);
// the upper line should be
invokeStatement(oldInstance, removeListenerMethodName, new Object[]{newL[i]}, out);

            }

It is obvious that if the for loop is executed, you are trying to access "oldL" with an illegal index because i >= oldL.length.
I think this may be a clerical error and "newL" should be used inside the for loop.

The exception will be thrown when we remove some default listeners from an instance. In one word, if oldL.length < newL.length,
an ArrayIndexOutOfBoundsException will be thrown.


REPRODUCIBILITY :
This bug can be reproduced occasionally.
