[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-9441) NPE during seam.ui tests running

[Viacheslav Kabanovich (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-9441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12618169#comment-12618169 ] 

Viacheslav Kabanovich commented on JBIDE-9441:
----------------------------------------------

According to the stack trace, this happens during shutdown, when web kb plugin is stopped before kb project state is saved. When saving starts, WebKbPlugin.getDefault() returns null. That never should happen while Eclipse is running, but it is normal during shutdown. The only way to fix this is to check that result is not null.
