[jbosstools-issues] [JBoss JIRA] (JBIDE-26697) Possible memory leak during Loading projects job when using CRC

[André Dietisheim (Jira)]

    [ https://issues.jboss.org/browse/JBIDE-26697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13802084#comment-13802084 ] 

André Dietisheim commented on JBIDE-26697:
------------------------------------------

The root cause here is that we're watching for changes for 12 resource types on different url. In consequence okHttp will open up connections and threads for each one of them. This results from the basic design principle of okHttp where they try not to have any blocking whatsoever:

So we have a dedicated thread for every socket that just reads frames and dispatches them.
