Subject [jira] [Commented] (NETBEANS-45) Code completion is blocked for an extended period of time
Date Tue, 25 Jul 2017 21:29:01 GMT

    [ https://issues.apache.org/jira/browse/NETBEANS-45?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16100817#comment-16100817
] 

Attila Kelemen commented on NETBEANS-45:
----------------------------------------

What I'm surprised about is that even if I don't touch anything but keep editting a single
file, this happens. Why does NB keep listing directories when nothing seems to happen? What
can trigger such a listing request?

> Often times when editting a single file, code completion blocks for an extensive amount
of time which makes code completion practically unusable. Looking at the threads of the IDE,
code completion and parsing seems to be blocked by the attached thread (holding a lock).
> Note that I do not do anything but edit a single file and this happens frequently during
editting even though there are no external changes.
