[Yura Zhishko (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-5542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12501070#action_12501070 ] 

Yura Zhishko commented on JBIDE-5542:
-------------------------------------

It seems like a duplicated of https://jira.jboss.org/jira/browse/JBIDE-5460 and was fixed in http://fisheye.jboss.org/changelog/JBossTools/?cs=19275. But Denis, could you provide me an environment (JBT/JBDS version) that you used to reproduce it?

> I cannot provide exact steps to reproduce it but stack trace tells me that that might happen for any none JBossTools project. For me it happens on project with JSF capabilities. To fix this problem on JBossTools JSF project, it should be closed/opened and VPE starts working.
