CLONE -StatelessKnowledgeSessions created by KnowledgeAgent causes NullPointerException when used in a pipeline --------------------------------------------------------------------------------------------------------------- Key: JBRULES-2194 URL: https://jira.jboss.org/jira/browse/JBRULES-2194 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler Environment: 5.0.1.SNAPSHOT for May 12, 2009 Reporter: Neil Wallace Assignee: Mark Proctor Fix For: 5.0.1.FINAL This issue is related to this thread on the user-list: http://www.mail-archive.com/rules-users@lists.jboss.org/msg08770.html I'm getting a NullPointerException when I insert an object into the pipeline using 5.0.1.SNAPSHOT from May 12, 2009: java.lang.NullPointerException at org.drools.runtime.pipeline.impl.StatelessKnowledgeSessionPipelineImpl.insert(StatelessKnowledgeSessionPipelineImpl.java:24) It looks like StatelessKnowledgeSession's ruleBase is null when created by the KnowledgeAgent, which poses a problem since StatelessKnowledgeSessionPipelineImpl invokes getRootClassLoader() on the session's ruleBase. Here's what I'm doing: StatelessKnowledgeSession ksession = kagent.newStatelessKnowledgeSession(); Pipeline pipeline = PipelineFactory.newStatelessKnowledgeSessionPipeline(ksession); pipeline.setReceiver(messageTransformer); pipeline.insert(message); // NPE here I'll attach a patch to KnowledgeAgentTest containing a failing test case. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
