[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-2641) taskService.addTaskParticipatingUser adds multiple participations for a user

by Robert Moskal (JIRA)

taskService.addTaskParticipatingUser adds multiple participations for a user ---------------------------------------------------------------------------- Key: JBPM-2641 URL: https://jira.jboss.org/jira/browse/JBPM-2641 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Environment: JDK 1.6 HSQL Reporter: Robert Moskal Perhaps this is the intended behavior, but calling taskService.addTaskParticipatingUser with the same user creates multiple participates: taskService.addTaskParticipatingUser(_task.getId(), "boss_rigging", Participation.CANDIDATE); taskService.addTaskParticipatingUser(_task.getId(), "boss_rigging", Participation.CANDIDATE); assertEquals(1,taskService.createTaskQuery().candidate("boss_rigging").activityName("Investigate").list().size()); The query comes back with two tasks.

[JBoss JIRA] Created: (JBPM-2642) A patch to support DB2 on zOS

by Richard L. Burton III (JIRA)

A patch to support DB2 on zOS ----------------------------- Key: JBPM-2642 URL: https://jira.jboss.org/jira/browse/JBPM-2642 Project: jBPM Issue Type: Patch Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.8, jBPM 3.2.7 Environment: Java version: 1.6.0_16,Sun Microsystems Inc., OS-System: Windows XP 5.1,x86, jboss-soa-p.4.3.0, DB2, version: DSN09015, Hibernate 3.2.4.sp1.cp08 Reporter: Richard L. Burton III Priority: Blocker Attachments: findJobsWithOverdueLockTime.patch When using jBPM with DB2 on zOS the JobSession object throws an exception when trying to find jobs with overdue lock time. The exception thrown is: DB2 SQL error: SQLCODE: -180, SQLSTATE: 22007, SQLERRMC: 1 I attached a patch which corrects this problem. Currently JobSession#findJobsWithOverdueLockTime(Date) is using Query#setDate(..) instead of Query#setTimestamp(...) This isn't a problem when using the DB2 Universal version on windows, only on zOS. -- 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

by Taro Yasuma (JIRA)

Document JbpmSchema API and ant task ------------------------------------ Key: JBPM-2164 URL: https://jira.jboss.org/jira/browse/JBPM-2164 Project: JBoss jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.6.SP1 Reporter: Taro Yasuma Document JbpmSchema API and ant task. For instance, to drop jBPM schema you can use the two ways. Programatically: JbpmSchema.dropSchema() Through Ant: <jbpmschema output="${scriptsdir}/jbpm.jpdl.postgresql.sql" config="hibernate.cfg.postgresql.xml" action="drop" delimiter=";"/> We need to elaborate how to use those in our docs. -- 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

[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-2703) Deserialization fails to work using custom Classloader

by Nicolas Leroux (JIRA)

Deserialization fails to work using custom Classloader ------------------------------------------------------ Key: JBPM-2703 URL: https://jira.jboss.org/jira/browse/JBPM-2703 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Reporter: Nicolas Leroux Fix For: jBPM 4.x I am trying to use jBPM outside a servlet container and when storing a variable in the execution context, retrieving it I have: Caught: java.lang.ClassNotFoundException: Blah This is the same bug as described in: http://jira.codehaus.org/browse/GROOVY-1627 . I think this is the following issue as well: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4340158 . {quote}Java uses the last defined ClassLoader to loader the class. In many environments this might mean that the wrong class loader is chosen or that it works one day and the other day not. {quote} The following code fixes the problem (in org.jbpm.pvm.internal.type.converter.SerializableToBytesConverter line 71 in the revert method: {code} ObjectInputStream ois = new ObjectInputStream(bais) { protected Class resolveClass(ObjectStreamClass objectStreamClass) throws IOException, ClassNotFoundException { return Class.forName(objectStreamClass.getName(), true, Thread.currentThread().getContextClassLoader()); } }; {code} -- 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
