[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

evaluate the previous methods ----------------------------- Key: JBPM-1288 URL: http://jira.jboss.com/jira/browse/JBPM-1288 Project: JBoss jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: PVM Reporter: Tom Baeyens this relates to Execution.getPreviousNode() Execution.getPreviousTransition() Node.isPreviousNeeded() Comment in Execution.java: // TODO evaluate the previous methods // these methods are kind of performance optimisations. a sequence and // some other specific control flow implementations can be optimised if they // have access to the previous node or transition. // Those activities could also be implemented by letting the activities store // the contextual information in process variables or some other execution // context. But with the previous properties as done now, these control flow // nodes can be implemented without storing an extra record. It's only a property // that is only updated when the node configuration indicates that it's needed. // (see also Node.isPreviousNeeded()) -- 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-1236) fix for undescriptive NullPointerException when jbpm4jsf-config.xml is missing

by Gergely Nagy (JIRA)

fix for undescriptive NullPointerException when jbpm4jsf-config.xml is missing ------------------------------------------------------------------------------ Key: JBPM-1236 URL: http://jira.jboss.com/jira/browse/JBPM-1236 Project: JBoss jBPM Issue Type: Patch Security Level: Public (Everyone can see) Components: Web Interface Reporter: Gergely Nagy An undescriptive error page is shown when jbpm4jsf-config.xml is missing: simple error 500 page with no indication to the cause of the error. I could only track this down by debugging jbpm4jsf, and it took me a while to figure this out. The attached patch includes a check for null, and a descriptive error message. -- 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
