[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-3818) ConcurrentModificationException in seam validator

Wed Feb 18 06:26:44 EST 2009

    [ https://jira.jboss.org/jira/browse/JBIDE-3818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12453056#action_12453056 ] 

Viacheslav Kabanovich commented on JBIDE-3818:
----------------------------------------------

I vote for making a copy of components collection. 
Iteration in SeamCoreValidator.validateAll takes a lot of time, about 1 minute per 1000 components, and for that time model is expected to be locked. Making a copy is 1000 times faster. If model is going to be modified during validation of that copy, another validator job will be queued, and in the end actual set of components will be validated.
