ConcurrentModificationException in ExtensibleContributionListener -----------------------------------------------------------------
Key: TUSCANY-2092 URL: https://issues.apache.org/jira/browse/TUSCANY-2092 Project: Tuscany Issue Type: Bug Reporter: Greg Dritschler java.util.ConcurrentModificationException at java.util.AbstractList$SimpleListIterator.next(Unknown Source) at org.apache.tuscany.sca.contribution.service.ExtensibleContributionListener.contributionAdded(ExtensibleContributionListener.java:40) at org.apache.tuscany.sca.contribution.service.impl.ContributionServiceImpl.addContribution(ContributionServiceImpl.java:389) at org.apache.tuscany.sca.contribution.service.impl.ContributionServiceImpl.contribute(ContributionServiceImpl.java:202) The problem occurs if two threads try to add a contribution simultaneously. DefaultContributionListenerExtensionPoint does not synchronize the list of listeners. In particular loadListeners does not prevent multiple threads from trying to load the list of listeners. One thread completes first while the other is still loading. This leads to the exception shown above when a thread tries to iterate the listener list. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
