[JBoss JIRA] Created: (JBPM-2948) Resume super process execution in separate transaction

by Alejandro Guizar (JIRA)

Resume super process execution in separate transaction ------------------------------------------------------ Key: JBPM-2948 URL: https://jira.jboss.org/browse/JBPM-2948 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Reporter: Alejandro Guizar Assignee: Alejandro Guizar Fix For: jBPM 3.2.10 [Description by Brad Davis] Consider a process with forks and joins that internally call sub-processes. Sub-processes wait for a number of minutes doing some stuff, and then they end. If the sub-processes all end at the same time, they try to signal the token for the parent process and get a stale object exception. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2422) investigate if logging abstraction should be removed

by Tom Baeyens (JIRA)

investigate if logging abstraction should be removed ---------------------------------------------------- Key: JBPM-2422 URL: https://jira.jboss.org/jira/browse/JBPM-2422 Project: JBoss jBPM Issue Type: Task Security Level: Public (Everyone can see) Reporter: Tom Baeyens Priority: Minor Fix For: jBPM 4.x the current approach is to have a minimal log framework pluggability: ---------------------------------------------------------------------------------------------- 1) jdk logging because we want it to be possible to run pvm without external library dependencies 2) log4j as jboss doesn't include a jdklogging-to-log4j bridge. general links ------------------ http://www.jboss.org/community/wiki/Logging select between these options: ----------------------------------------- 1) always require a jbpm.logging.properties on the classpath. that configures the jdk logging. eithers completely, or with a delegation to log4j in that case our jbpm code can always use the jdk logging. 2) keep it as it is 3) similar solution to seam for facelets: ===http://markmail.org/message/ywamc5yc7hejrlls==================================================================== Subject: Facelets JDK Logging -> JBoss Log4j bridge Actions... From: Pete Muir (pmu...(a)bleepbleep.org.uk) Date: Feb 19, 2008 7:27:50 am List: net.java.dev.facelets.dev As has been discussed many times on the seam forum and facelets mailing list, JBoss AS doesn't have a jdk logger -> log4j generic bridge (I don't know why, and I don't really want to find out) so what Stan did for JSF RI was write a JDK logging filter that would bridge JUL to log4j. I have done the same for Facelets (included as part of jboss-seam-ui.jar, I can factor out the relevant code if anyone wants it) but hit a sight problem. Most logs in facelets are declared protected static final (so I can get at them using reflection) but in DefaultFacelet, CompositionHandler and DecorateHandler they are protected final (so I can't get at them easily as they aren't static). Any chance they could become static? Let me know and I'll file a bug. Code is here http://fisheye.jboss.org/browse/Seam/trunk/ui/src/main/java/org/jboss/sea...

[JBoss JIRA] Created: (JBPM-2930) IllegalArgumentException on error path in DispatcherThread

by Per Christian Henden (JIRA)

IllegalArgumentException on error path in DispatcherThread ---------------------------------------------------------- Key: JBPM-2930 URL: https://jira.jboss.org/browse/JBPM-2930 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4 Environment: JBPM 4.4 upgraded from 4.3, JDK 1.6u21. Reporter: Per Christian Henden DispatcherThread waits before retrying to execute a Job when there is an error. If there are multiple failures in a row, the wait period is increased in the following manner: int currentIdleInterval = jobExecutor.getIdleMillis(); //Typically a few seconds while(isActive) { .... catch (Exception e) { ... semaphore.wait(currentIdleInterval); ... currentIdleInterval = currentIdleInterval * 2; ... } } In other words, currentIdleInterval grows without bounds. Eventually the integer currentIdleInterval will overflow and semaphore.wait() will throw java.lang.IllegalArgumentException: timeout value is negative, resulting in a crash. In my case an error occurs because there are timers that refer to inactive executions (because timers that have not fired are not deleted when a subprocess ends in JBPM 4.3). This has left me with some 340 rows in JBPM4_JOB that refers to a non-existing execution. Another aspect of this problem is that the retry-wait can grow to unreasonably large values, for example multiple days, and if my calculations are correct, multiple years. A simple fix is to introduce an upper bound of for example 256 * jobExecutor.getIdleMillis(), and not increase currentIdleInterval above that. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2688) extend ProcessInstanceQuery so that process instances can be searched by their processDefinitionKeys

by Sebastian Schneider (JIRA)

extend ProcessInstanceQuery so that process instances can be searched by their processDefinitionKeys ---------------------------------------------------------------------------------------------------- Key: JBPM-2688 URL: https://jira.jboss.org/jira/browse/JBPM-2688 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Reporter: Sebastian Schneider When using a ProcessInstanceQuery it is possible to search by processBusinessKey and also by processDefinitionId. The ProcessInstanceQuery should be extended so that process instances can also be searched by processDefinitionKeys. This is usel in situations where you want to retrieve all process instances of the same process definition but in different versions. -- 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-2938) Missing attributes in jpdl-4.4.xsd

by James Baker (JIRA)

Missing attributes in jpdl-4.4.xsd ---------------------------------- Key: JBPM-2938 URL: https://jira.jboss.org/browse/JBPM-2938 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Documentation, Runtime Engine Affects Versions: jBPM 4.4 Environment: Windows Vista, JBoss EAP 5.0 Reporter: James Baker The 4.4 XSD does not allow the "name" attribute for <object /> or <ref /> elements which means that they cannot be used for HQL activity parameters which require a name. I have noted that if you just ignore the XSD and specify a name anyway it does work (org.jbpm.pvm.internal.wire.descriptor.AbstractDescriptor defines a field "name"). Also it's worth pointing out that neither the user guide or examples provide an example on an HQL activity with a parameter from the execution context. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2929) ClassCastException after reading serialized variable

by Marcus Klimstra (JIRA)

ClassCastException after reading serialized variable ---------------------------------------------------- Key: JBPM-2929 URL: https://jira.jboss.org/browse/JBPM-2929 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Environment: Windows XP, Java 6 Reporter: Marcus Klimstra Related to JBPM-2703. I have a process definition with two custom nodes, refering to ActivityBehaviour classes Custom1 and Custom2. Class Custom1 sets a process variable named "bean" of class Bean, and Custom2 reads and uses this variable: {code} public class Bean implements Serializable { private int value; public int getValue() { return value; } public void setValue(int value) { this.value = value; } } public class Custom1 implements ActivityBehaviour { public void execute(ActivityExecution execution) throws Exception { Bean bean = new Bean(); bean.setValue(42); execution.setVariable("bean", bean); } } public class Custom2 implements ActivityBehaviour { public void execute(ActivityExecution execution) throws Exception { Bean bean = (Bean)execution.getVariable("bean"); if (bean.getValue() != 42) { throw new Exception("Value must be 42!"); } } } {code} All these classes were added to the deployment using addResourcesFromZipInputStream/addResourceFromInputStream. So far this works fine. However, when I put a task node between custom1 and custom2 (apparently causing the variable to be serialized?), things go awry: {code} java.lang.ClassCastException: [...].Bean cannot be cast to [...].Bean at [...].Custom2.execute(Custom2.java:6) at org.jbpm.pvm.internal.wire.usercode.UserCodeActivityBehaviour.execute(UserCodeActivityBehaviour.java:42) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform(ExecuteActivity.java:60) at ...etc... {code} So it seems that there are two Bean-classes, loaded by different classloaders. I've traced this problem to the DeploymentObjectInputStream, which creates a new DeploymentClassLoader each time it enters the catch-clause. Since the second Bean-class is loaded by a different classloader, it is incompatible with the first. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
