NullPointerException in the Eclipse plugin ------------------------------------------ Key: JBPM-963 URL: http://jira.jboss.com/jira/browse/JBPM-963 Project: JBoss jBPM Issue Type: Bug Affects Versions: jBPM jPDL 3.2 Environment: WinXP SP2 Eclipse 3.2.1, JDK 1.5.0_11 and/or JDK 1.4.2_13 Reporter: Oleksandr Alesinskyy Hello, I have downloaded and installed jBPM suite 3.2GA then I have installed Eclipse plugin from that suite into pre-existing Eclipse 3.2.1 (by copying contents of designer/eclipse directory to Eclipse extesions directory) and have created new JBoss JBPM Process project (with sample contents) - all succesfully. Then I have checked in the project into CVS. After this on Eclise restart comes message "Can not initialize JDT tooling" and following error stack: java.lang.NullPointerException at org.jbpm.ui.util.JbpmClasspathContainer.getJarNames(Unknown

The same occurs if I install plugin on other computer and check-out the project and restart Eclipse. I#m still able to create another new jBPM Process project and work with it.
