---------------------------------------------
So what happens when you use jdk1.8.0_05 under both?
> Find usages is very slow in Netbeans 9.0 and it sits a long time at
> Initializing data and Usages progress bars without showing any progress at all

> Key: NETBEANS-1269
> URL: https://issues.apache.org/jira/browse/NETBEANS-1269
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 9.0
> Environment: Netbeans 9.0 based on jdk-10.0.1 on Windows 10 Pro
> Reporter: Ciprian Bulboaca
> Priority: Critical
>
> Find usages in Netbeans 9.0 is very slow (compared to Netbeans 8.0.2).
> For example, in our large modular project we have, doing a find usages on any
> method in any class takes a very long time (4-5 minutes) in Netbeans 9.0. For
> about half the time, Netbeans 9.0 is just sitting at "Initializing data" and
> for the other half, it is just sitting at Usages progress bar always showing
> 0% progress! Then, after a long period of waiting, it just shows the results
> without even updating the progress bar (or at least you can't tell it is
> updating the progress bar).
> This all behaves normally under Netbeans 8.0.2 where find usages is showing
> results right away (as it's scanning) and the whole process takes only a few
> seconds!
> We've tried bumping up the -J-Xmx setting to 1536m in netbeans.conf and
> although we see the memory allocated is increasing (in Task Manager),
> Netbeans 9.0 behaves the same way.
> I'm wondering if anybody else is experiencing this. Is there any workaround
> for this issue? This affects our day to day work very significantly since we
> rely on fast 'find usages' operations all the time in our analysis & coding
> work.
