<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Is there some magic going on in ProcessInstanceInfo? As far as I can tell there is no way that the processInstanceId can ever have a non-null value. This causes a null pointer exception
 when called from JPAProcessInstanceManager line 37  because it will try and unbox null to a long.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Can anyone explain what is supposed to happen?</p>
