[jira] [Created] (NETBEANS-2354) ArrayIndexOutOfBoundsException
during "Find Usages" operation
Travis created NETBEANS-2354:
--------------------------------
Summary: 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
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!
