[jbosstools-issues] [JBoss JIRA] (JBIDE-19376) Eclipse freezes at or shortly after startup

[Rob Stryker (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-19376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13044496#comment-13044496 ] 

Rob Stryker commented on JBIDE-19376:
-------------------------------------

I don't think we should move it into ServerCorePlugin. I think the constructor for UnifiedServerListenerManager should launch a thread to initialize itself.  ServerCorePlugin.start() needs to return quickly and not be doing so much stuff in wst.server.core, because it's probably triggering even more loading and potentially even loops once extension points are brought in. 

So I think we need ServerCorePlugin.start to complete as quick as possible and do as little as possible. But the other danger is that if others add listeners to UnifiedServerListenerManager that get missed, ie,  UnifiedServerListenerManager  has already started adding listeners to wst.server.core,  and someone adds a new listener to UnifiedServerListenerManager   which doesn't get added to wst.server.core. 

I'll look into it more tomorrow.

> Sometimes (probably once or twice a month) my eclipse freezes either right at startup or short after startup if I try to save some modified file. In Java VisualVM I can see than a deadlock in org.jboss.ide.eclipse.as.core.JBossServerCorePlugin.start() method.
> Today I have updated JBoss plugins to latest version (from the update site for JBoss Tools 4.2.2.Final) and was able to reproduce the problem at every second or third startup . It looks like it occurs on larger workspaces (my current workspace has about 70 open projects (most of them are java projects and depends on each other)) and if servers view is open/visible right at startup. In a smaller workspace with only 11 projects I had no luck reproducing the deadlock.
