[JBoss JIRA] Created: (JBPM-1162) Problem with exception handling within the Decision nodes

by Jon Folland (JIRA)

Problem with exception handling within the Decision nodes --------------------------------------------------------- Key: JBPM-1162 URL: http://jira.jboss.com/jira/browse/JBPM-1162 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: Vaio laptop running Windows Vista, Java 1.5, JBPM 3.2.2 Reporter: Jon Folland Assigned To: Tom Baeyens I believe there may be a bug in the Decision class where exception handling is concerned which causes this failure: If the line: String transitionName = decisionHandler.decide(executionContext); ... ...in the method public void execute(ExecutionContext executionContext) throws an exception, which is caught here in the same method: raiseException(exception, executionContext); We miss the block: if (transition==null) { transition = getDefaultLeavingTransition(); log.debug("decision didn't select transition, taking default "+transition); } So when executionContext.leaveNode(transition); is called at the bottom, there wil be no transition set. I believe we need to check for a tranistion==null condition regardless of whether an excpetion has been handled. Otherwise you will never be able to handle an exception in a Decision without another unhandled exception being thrown (which kind of defeits the point :-) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1158) Missing query JobSession.findJobsWithOverdueLockTime in hibernate.queries.hbm.xml

by Julien Kronegg (JIRA)

Missing query JobSession.findJobsWithOverdueLockTime in hibernate.queries.hbm.xml --------------------------------------------------------------------------------- Key: JBPM-1158 URL: http://jira.jboss.com/jira/browse/JBPM-1158 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: zip file downloaded from http://www.jboss.org/downloading/?projectId=jbossjbpm&url=http://download... Reporter: Julien Kronegg Assigned To: Tom Baeyens The org.jbpm.db.JobSession class has a findJobsWithOverdueLockTime(Date) method which use a query named "JobSession.findJobsWithOverdueLockTime". In similar methods of the same class, the queries are located in org.jbpm.db.hibernate.queries.hbm.xml, which is not the case for this query. The "JobSession.findJobsWithOverdueLockTime" string could not be found elsewhere in the project. Conclusion: the "JobSession.findJobsWithOverdueLockTime" query seems to be missing in hibernate.queries.hbm.xml (or the method should be removed from the class). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1139) The ClassUtil class is not thread-safe

by Wojciech Gdela (JIRA)

The ClassUtil class is not thread-safe -------------------------------------- Key: JBPM-1139 URL: http://jira.jboss.com/jira/browse/JBPM-1139 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.3 Reporter: Wojciech Gdela Assigned To: Tom Baeyens Attachments: ClassUtil-concurrency-issue.zip The ClassUtil class is not thread-safe. The exception will occur when two thread simultanously try do deserialize variables from two different process definitions. Look at the code: {code} public ContextObjectInputStream(final InputStream in, ProcessInstance processInstance) throws IOException { super(in); this.setProcessInstance(processInstance); ClassUtil.setProcessInstance(processInstance); } ... protected Class resolveClass(final ObjectStreamClass desc) throws IOException, ClassNotFoundException { return ClassUtil.forName(desc.getName(), ContextObjectInputStream.class); } ... ContextObjectInputStream cois = new ContextObjectInputStream(bais, definition.createProcessInstance()); // when here another thread tries to execute the same code with another process instance there will be a problem return cois.readObject(); {/code} Further description of issue is in attached test case. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1178) Script conditions in transitions are evaluated as expressions by the decision node

by Romain Lamarche (JIRA)

Script conditions in transitions are evaluated as expressions by the decision node ---------------------------------------------------------------------------------- Key: JBPM-1178 URL: http://jira.jboss.com/jira/browse/JBPM-1178 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: Windows XP, JBoss AS 4.2.2GA, MS SQL EXPRESS 2005, Jdk5 Reporter: Romain Lamarche Assigned To: Tom Baeyens The decision node does not evaluate scripts in conditional transitions. Indeed, the execute method of node type decision does not check what type of condition it is. Listing of the wrong code : (file Decision.java lines 120-135 in Jbpm Jpdl 3.2.2) } else { // new mode based on conditions in the transition itself Iterator iter = leavingTransitions.iterator(); while (iter.hasNext() && (transition==null)) { Transition candidate = (Transition) iter.next(); String conditionExpression = candidate.getCondition(); if (conditionExpression!=null) { Object result = JbpmExpressionEvaluator.evaluate(conditionExpression, executionContext); if (Boolean.TRUE.equals(result)) { transition = candidate; } } } } The problem is the "JbpmExpressionEvaluator". -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
