[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3873) Memory leak using EJB transactions and jBpm contexts

by Torsten Fink (JIRA)

Memory leak using EJB transactions and jBpm contexts ---------------------------------------------------- Key: JBSEAM-3873 URL: https://jira.jboss.org/jira/browse/JBSEAM-3873 Project: Seam Issue Type: Bug Components: BPM, Core, EJB3 Affects Versions: 2.1.1.GA Environment: JBoss 4.2.x, Mac OSX and Linux environments, Java 1.5 Reporter: Torsten Fink Attachments: MemoryLeakEventKontext.tgz Our application had to survive a night with full load. On the next morning the heap was full of JbpmContext's. After looking at the source code of Seam and at the debug messages we came up with this hypothesis: * The SFSB EjbSynchronizations is placed in the event context, the Seam-JbpmContext-Component also lives in the event context. * Using EJB transactions, EjbSynchronizations is responsible for cleaning up the JbpmContext after the end of the transaction. * Unfortunately the event context ends BEFORE EjbSynchronizations has the chance to clean up the JbpmContext. Using BMT the transaction ends before the event context ends. Thus, the JbpmContext is cleaned up. We switch all our MDBs, EJB-timers, and Web-services from CMT to BMT and (after fixing some other leaks, e.g. a class loader issue in jBpm), we survived the night. I wrote a small test application that shows the memory leak and I will try to attach it to this issue. It is a Maven application that consists of - a Web-GUI to start the test and displays the results (http://localhost:8080/leak/) - a SFSB that sends 10 messages each to two queues (the standard queues A and B), waits a little bit, and does a gc - two MDBs, one with CMT, one with BMT, which uses Seam injection to access a jBpm-Context - an application scoped POJO that saves the contexts in a Set using a weak reference After executing the tests and the GC, the surviving references are displayed. You can see that the CMT references are not gs'ed whereas the BMT references are cleaned up. You can execute the test several times. -- 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

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2164) Improve exception chaining in SeamLoginModule

by Yannick Lazzari (JIRA)

Improve exception chaining in SeamLoginModule --------------------------------------------- Key: JBSEAM-2164 URL: http://jira.jboss.com/jira/browse/JBSEAM-2164 Project: JBoss Seam Issue Type: Feature Request Reporter: Yannick Lazzari Priority: Minor This an improvement request in the SeamLoginModule class to properly chain exceptions when throwing LoginExceptions in the login method. See code below: public boolean login() throws LoginException { try { NameCallback cbName = new NameCallback("Enter username"); PasswordCallback cbPassword = new PasswordCallback("Enter password", false); // Get the username and password from the callback handler callbackHandler.handle(new Callback[] { cbName, cbPassword }); username = cbName.getName(); } catch (Exception ex) { log.error("Error logging in", ex); throw new LoginException(ex.getMessage()); } MethodExpression mb = Identity.instance().getAuthenticateMethod(); if (mb==null) { throw new IllegalStateException("No authentication method defined - please define <security:authenticate-method/> for <security:identity/> in components.xml"); } try { return (Boolean) mb.invoke(); } catch (Exception ex) { log.error("Error invoking login method", ex); throw new LoginException(ex.getMessage()); } } In both instances where a LoginException is thrown, only the message is passed to the constructor of the LoginException. I know that the LoginException does not overload the constructor to pass a cause directly but we can use the initCause method instead: LoginException loginException = new LoginException(); loginException.initCause(originalException); throw loginException; If people use typed exceptions in their authenticator method to express different reasons why the login attempt failed, it's impossible right now to get that original exception. -- 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

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3833) Be able to find out the Event type in observers

by Sanne Grinovero (JIRA)

Be able to find out the Event type in observers ----------------------------------------------- Key: JBSEAM-3833 URL: https://jira.jboss.org/jira/browse/JBSEAM-3833 Project: Seam Issue Type: Feature Request Components: Core Reporter: Sanne Grinovero To "find out" I mean programmatically. As the same method could be listening for more Events, it's possible we need actually to detect all types, not just one, or be sure to be fired once for each event. This is a requirement for PBR-58 -- 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

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1758) DocumentStorePhaseListener fails if installed before SeamPhaseListener when used in a portlet

by Chris Rudd (JIRA)

DocumentStorePhaseListener fails if installed before SeamPhaseListener when used in a portlet --------------------------------------------------------------------------------------------- Key: JBSEAM-1758 URL: http://jira.jboss.com/jira/browse/JBSEAM-1758 Project: JBoss Seam Issue Type: Bug Affects Versions: 2.0.0.BETA1 Reporter: Chris Rudd When the DocumentStorePhaseListener is installed before the SeamPhaseListener (this can happend when the jboss-seam.jar sits in the ear, and the jboss-seam-pdf.jar sits in the war) in a portlet environment, a "No active application context" exception is thrown during Portlet.render. This is becaus the SeamPhaseListener hasn't had a chance to setup the Seam contexts yet. I would suggest changing the code so that it responds to the Phase events that the SeamPhaseListener publishes ( org.jboss.seam.beforePhase ) so that its guaranteed to be executed after the SeamPhaseListener has property set things up. -- 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

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2253) UIHeaderFooter should allow different elements than just Phrase

UIHeaderFooter should allow different elements than just Phrase --------------------------------------------------------------- Key: JBSEAM-2253 URL: http://jira.jboss.com/jira/browse/JBSEAM-2253 Project: JBoss Seam Issue Type: Feature Request Components: PDF Affects Versions: 2.0.0.GA Reporter: Bolke de Bruin Currently the UIHeaderFooter does not allow anything else than Text (Phrase). This makes it unusable to generate something with for example a company logo on every page.
