Hi Bjoern, did you use the proposed solution in your project? I wanted to use it for an own problem with classloading (and I can also commit it back to jbpm after it works correctly) but have the problem, that this is leading to and endless loop, since the classloader is already needed to load the jbpm.cfg.xml in the JbpmConfiguration (InputStream jbpmCfgXmlStream = ClassLoaderUtil.getStream(resource);). Exception StackTrace: | at org.jbpm.util.ClassLoaderUtil.getClassLoader(ClassLoaderUtil.java:50) | at org.jbpm.util.ClassLoaderUtil.getStream(ClassLoaderUtil.java:83) | at org.jbpm.JbpmConfiguration.getInstance(JbpmConfiguration.java:279) | at org.jbpm.JbpmConfiguration.getInstance(JbpmConfiguration.java:257) | at org.jbpm.JbpmConfiguration$Configs.getObjectFactory(JbpmConfiguration.java:418) | at org.jbpm.JbpmConfiguration$Configs.hasObject(JbpmConfiguration.java:426) | at org.jbpm.util.ClassLoaderUtil.getClassLoader(ClassLoaderUtil.java:50) | How did you solve this?
