jBPM classloader does not define package information ---------------------------------------------------- Key: JBPM-1447 URL: https://jira.jboss.org/jira/browse/JBPM-1447 Project: JBoss jBPM Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Kevin Conner Assignee: Thomas Diesler Priority: Critical The jBPM ProcessClassLoader defines classes from within the par file but it does not define the associated package information. As a consequence the result of <class>.getPackage() is null and code which relies on this (such as JAXB for package annotations) will not work. A simple fix would be to add the following to the findClass method although it should be noted that this ignores the manifest/sealing information. if (fileDefinition!=null) { // Add the package information final int packageIndex = name.lastIndexOf('.') ; if (packageIndex != -1) { final String packageName = name.substring(0, packageIndex) ; final Package classPackage = getPackage(packageName) ; if (classPackage == null) { definePackage(packageName, null, null, null, null, null, null, null) ; } } With this fix in place the JAXB marshalling works as expected.
