[jbosstools-issues] [JBoss JIRA] (JBIDE-18506) Usage plugin sometimes locks JBT/JBDS

[Alexey Kazakov (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-18506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009385#comment-13009385 ] 

Alexey Kazakov commented on JBIDE-18506:
----------------------------------------

Anyway, it's too risky to make big changes in how loading/initiolization usage and its settings in 4.2.0.
This PR is simple and safe enough though.

> JBossToolsUsageActivator initializes settings when starting and calls
> AbstractEclipseEnvironment.initScreenSettings()
> that uses the Display.syncExec method 
> which causes JBT/JBDS to freeze. The issue isn't always reproducible, but it often happens when starting JBDS/JBT in a new workspace.
> While I was testing JBIDE-16379, I reproduced it each time when I started Eclipse 4.4.1/JBT 4.2.0.CR1 in a new workspace.
