Steps to Reproduce:

Hide

How reproducible:
Edit the seam 'numberguess' example in EAP 5.1.2 so pageflow.jpdl.xml uses
this:
<decision name="evaluateGuess" expression="#
{numberGuess.isCorrectGuess()}
">
instead of:
<decision name="evaluateGuess" expression="#
{numberGuess.correctGuess}
">

Steps to Reproduce:
1. Change pageflow.jpdl.xml as above
2. build seam/numberguess and deploy to EAP 5.1.2
3. Run the example. It should fail with a CCE at line 99 for Decision.java in
jBPM 3.2.10.

Seam throws a ClassCastException when jBPM is accessing a Boolean property. This used to work, but changes in between jBPM3.2.5 and 3.2.10 broke it.
