[JBoss JIRA] Created: (JBPM-1912) org.jbpm.taskmgmt.exe.TaskMgmtInstance.getTaskInstances() should return a clone or an unmodifiable view, otherwise documentation should explain it does not

by Mauro Molinari (JIRA)

org.jbpm.taskmgmt.exe.TaskMgmtInstance.getTaskInstances() should return a clone or an unmodifiable view, otherwise documentation should explain it does not ----------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBPM-1912 URL: https://jira.jboss.org/jira/browse/JBPM-1912 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: API Affects Versions: jBPM 3.3.0 GA Reporter: Mauro Molinari The method org.jbpm.taskmgmt.exe.TaskMgmtInstance.getTaskInstances() returns directly the set internally used by the TaskMgmtInstance instance to track task instances, without cloning it. This can cause client code to corrupt that set (adding or removing elements in it) and corruption is "propagated" to all the task instances that share the same TaskMgmtInstance instance. I think that method should return a clone or an unmodifiable view of that set, otherwise the Javadoc should state clearly that it does not, warning the client programmer of the inherent risks. A similar rule may apply to org.jbpm.taskmgmt.exe.TaskMgmtInstance.getTaskInstancesWithVariableUpdates() too. -- 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-1716) NPE in Transition.fireSuperStateEnterEvents() when destination is null

by Karl Palsson (JIRA)

NPE in Transition.fireSuperStateEnterEvents() when destination is null ---------------------------------------------------------------------- Key: JBPM-1716 URL: https://jira.jboss.org/jira/browse/JBPM-1716 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Core Engine Affects Versions: jBPM 3.2.3 Reporter: Karl Palsson The current method body is shown below. Destination is null in my case (I should check my process definition, it came about from a bad database move) However, instead of getting the JbpmException shown, I get the NPE from the "destination.isSuperStateNode()" loop above. I'm not entirely sure what that loop is for, which is why I've not included a patch here. I'm unsure whether it should be moved down just past the first null check, or to the very bottom. Sorry :( Source in question... Node fireSuperStateEnterEvents(ExecutionContext executionContext) { // calculate the actual destinationNode node Node destination = to; while (destination.isSuperStateNode()) { ###KJP This explodes before it gets to the Null check 3 lines down. destination = (Node) destination.getNodes().get(0); } if (destination==null) { String transitionName = (name!=null ? "'"+name+"'" : "in node '"+from+"'"); throw new JbpmException("transition "+transitionName+" doesn't have destination. check your processdefinition.xml"); } // performance optimisation: check if at least there is a candidate superstate to be entered. if ( destination.getSuperState()!=null ) { // collect all the superstates being left List leavingSuperStates = collectAllSuperStates(destination, from); // reverse the order so that events are fired from outer to inner superstates Collections.reverse(leavingSuperStates); // fire a superstate-enter event for all superstates being left fireSuperStateEvents(leavingSuperStates, Event.EVENTTYPE_SUPERSTATE_ENTER, executionContext); } return destination; } -- 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-1765) Unclosed InputStream in org.jbpm.util.ClassLoaderUtil.getProperties

by Tim Timson (JIRA)

Unclosed InputStream in org.jbpm.util.ClassLoaderUtil.getProperties ------------------------------------------------------------------- Key: JBPM-1765 URL: https://jira.jboss.org/jira/browse/JBPM-1765 Project: JBoss jBPM Issue Type: Quality Risk Security Level: Public (Everyone can see) Affects Versions: jBPM 3.2.2 Environment: Glassfish v2 Reporter: Tim Timson Fix For: jBPM 3.3.0 GA Our Glassfish server logs a stack trace every time we undeploy our app. It looks like this is because you are not closing an input stream in the "getProperties" method of the org.jbpm.util.ClassLoaderUtil class. Note that the "Properties.load" method does not close the input stream (unlike the "Properties.loadFromXml" method which does close the input stream). It looks like there is one case where you use Properties.load, and in that case you are not closing the input stream. -- 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-1148) jBPM Classloading

by Bjoern Wand (JIRA)

jBPM Classloading ----------------- Key: JBPM-1148 URL: http://jira.jboss.com/jira/browse/JBPM-1148 Project: JBoss jBPM Issue Type: Patch Components: Core Engine Reporter: Bjoern Wand Assigned To: Tom Baeyens jBPM does not use ContextClassloader for classloading.

[JBoss JIRA] Created: (JBPM-1307) jBPM tries to use Hibernate transaction even if configured with isTransactionEnabled = false

by Mauro Molinari (JIRA)

jBPM tries to use Hibernate transaction even if configured with isTransactionEnabled = false -------------------------------------------------------------------------------------------- Key: JBPM-1307 URL: http://jira.jboss.com/jira/browse/JBPM-1307 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Core Engine Affects Versions: jPDL 3.2.2 Reporter: Mauro Molinari The method org.jbpm.scheduler.db.DbSchedulerService.deleteTimersByProcessInstance(ProcessInstance) is accessing the Hibernate transaction even if jBPM is configured not to use transactions: <service name="persistence"> <factory> <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory"> <field name="isTransactionEnabled"> <false /> </field> <field name="isCurrentSessionEnabled"> <true /> </field> </bean> </factory> </service> This causes a serious problem when you're using jBPM inside a JTA environment and you want to control JTA transactions by yourself. For instance, we're using Spring to manage transactions a JBoss Transactions as the JTA implementation. We are not using JNDI in any way, but when we try to call processInstance.end(), a call to org.jbpm.scheduler.db.DbSchedulerService.deleteTimersByProcessInstance(ProcessInstance) is performed and Hibernate tries to create a new JTATransaction by querying an empty JNDI InitialContext. The only workaround we could find is the one outlined here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117325#4117325 that is, subclassing JobSession in order to use Spring TransactionSynchronizationManager. -- 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-1908) Provide a standalone package alongside the installer or make the installer cover more use-cases

by Mauro Molinari (JIRA)

Provide a standalone package alongside the installer or make the installer cover more use-cases ----------------------------------------------------------------------------------------------- Key: JBPM-1908 URL: https://jira.jboss.org/jira/browse/JBPM-1908 Project: JBoss jBPM Issue Type: Release Security Level: Public (Everyone can see) Components: Installer Affects Versions: jBPM 3.3.0 GA Reporter: Mauro Molinari The current 3.3.0GA installer does not cover all the uses cases for jBPM download needs. For instance, if I need to download just jBPM standalone (maybe together the GPD), without needing any deployment phase, now I can't, because the installer forces you to specify a JBoss Server and a DBMS for server-side deployment. The trick is to specify an empty folder for any of the JBoss Server version previously chosen. My suggestion is to either: 1) provide a plain ZIP with jBPM JARs, so that anyone can download it to get just jBPM JARs and do his own "manual" deployment 2) improve the installer so that it allows the user so skip the deployment phase and just uncompress its contents IMHO, the best solution would however be to provide both a plain ZIP and an improved installer. By the way, I don't need any automatic deployment because I'm using jBPM embedded into another web application that uses a plain application server with Spring Framework. -- 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

jBPM web console not properly showing task instance variables stored as byte array. ----------------------------------------------------------------------------------- Key: JBPM-1799 URL: https://jira.jboss.org/jira/browse/JBPM-1799 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Console Affects Versions: jBPM 3.2.2 Environment: weblogic 9.2, Oracle, jdk1.5, windows XP Reporter: santosh gadkari Fix For: jBPM 3.2.2 Steps to reproduce 1) Create a task instance with task instance variable as byte array. 2) open the saved task in jBPM console and see the variable which stored as byte array. It shows something like "[B@1d1fda ". which is the toString() output of byte array. -- 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
