[jbosstools-issues] [JBoss JIRA] (JBIDE-17842) local-jvm jmx monitor jmx provider freezing UI

[Rob Stryker (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-17842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12983791#comment-12983791 ] 

Rob Stryker commented on JBIDE-17842:
-------------------------------------

[~olpf]  last question:   does it freeze the workspace entirely forever (ie deadlock, only solvable by restart?) or does it just freeze the UI for a short while? 

I think my patch will properly handle that. I remove some synchronized keywords, synchronize only in smaller blocks, and ensure that the jps command is never run in the UI thread.  This would fix deadlocks as well as just a blocking UI. The only downside is some processes may be given a non-descript label in the JMX explorer until the JPS command completes... like "Unknown" or something.

> I reported that sometimes eclipse is freezing when jboss is synchronizing or starting and somebody told me to do a jstack on the eclipse process. Here is the ouput. Eclipse is totaly freezed with circle mouse pointer and in the right bottom corner "Starting JBoss AS 7.1: (0%)" is displayed. But JBoss is running in behind (my web app can be used).
