<div class="jive-rendered-content"><p>Hi Maciej,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks for your prompt response.  I took your advice and upgraded to jbpm 5.4.0CR1 and drools 5.5.0CR1.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>However, I am receiving this error when I load up a bpmn2 resource into the knowledge builder.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><strong>ProcessLoadError: unable to parse xml : Exception class java.lang.NullPointerException : null</strong></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>This happens when the kbuilder is adding the BPMN xml.  This is the same XML file that was used previously, so I'm not sure what would cause this error.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>By the way, I have done a LOT of jar re-packaging due to our OSGi environment.  The way in which jBPM/Drools packages jars is not an easy integration task b/c of split-packages, classes not being loaded properly, etc... It's been quite a headache just to get these bundles resolved.  So I've resorted to merging packages when necessary.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>But that aside, any idea why I might be getting the above error?</p></div>
