Geertjan Wielenga commented on NETBEANS-2671:
---------------------------------------------
Maybe if using a later JDK, switch to JDK 8, to see if there’s a difference, in
order to establish where the problem is coming from.
> NetBeans 11 unbearbly slow due to infinite scanning of projectsa
> ----------------------------------------------------------------

> Key: NETBEANS-2671
> URL: https://issues.apache.org/jira/browse/NETBEANS-2671
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 11.0
> Environment: Windows 10 64
> Reporter: Grzegorz
> Priority: Critical
>
> As netbeans is best program ever to edit PHP code for me, it has one flaw
> since 8.0. It can sometimes hang on background scanning without any reason.
> What I tried:
> - Restart
> - Cache Clear
> - Project delete and create new one
> - Also Disabled: Menu -> Tools -> Options -> Miscellaneus -> Files -> Enable
> auto-scanning
> Problem occurs on every start of netbeans with startup scan.
> Cannot cancel scan.
> Added not needed dirs into ignore folders.
>
> Below is exception from log.
