> ArrayIndexOutOfBoundsException during "Find Usages" operation
> -------------------------------------------------------------
>
> Key: NETBEANS-2354
> URL: https://issues.apache.org/jira/browse/NETBEANS-2354
> Project: NetBeans
> Issue Type: Bug
> Components: java - Refactoring
> Affects Versions: 11.0
> Reporter: Travis
> Priority: Major
>
> I'm using Netbeans 11 vc4 on Java 8 multi-project (on Windows). I ran "Find
> Usages" on a method and got the exception below. After this exception, the
> find results were empty, despite there being callers of the method within the
> search scope.
>
> I have spent a ton of time working with the same project using Netbeans 10,
> and running "Find Usages" frequently. I never got this exception there
> before, and Find Usages has been totally robust until now. So it seems this
> is likely a new bug in Netbeans 11.
>
> I cannot provide the gigantic multi-project where this problem is
> reproducible. I could try to reduce it down to a minimal testcase and then
> obfuscate the code, if you need an example project to reproduce this issue or
> to test the fix.
>
> Thanks!
