Comment 1 Markus Keller

2010-08-30 14:37:08 EDT

Any context? We've had a similar issue before (bug 144249), but that has been fixed for 3.6.

Comment 2 Ray Sinnema

2010-08-31 00:38:50 EDT

Sorry, can't provide any more details. I just tried a Rename refactoring and got this error consistently in that particular instance. Normally it works fine, and I didn't see any special circurmstances :(

Comment 3 Markus Keller

2010-08-31 09:39:37 EDT

I'll close this bug for now, please reopen if you see it again.

*** Bug 420263 has been marked as a duplicate of this bug. ***

I'm now seeing this error occurring in latest photon release.  I'm seeing the same stacktrace.

If you are able to provide steps for reproducing please do so and re-open the bug.

Comment 7 Nicola Orru

Just seen this:
- Rust Corrosion plugin

- org.eclipse.corrosion (0.3.0.201812040953) "Rust edition in Eclipse IDE" [Active]
- org.eclipse.lsp4e (0.8.0.201812101009) "Language Server Protocol client for Eclipse IDE (Incubation)" [Active]


Steps to reproduce
- Open a Rust source file in text editor
- Rename a symbol -> generally works the first time
- Rename more symbols, repeat many times, eventually this error shows up.

Did you mean to report this against Corrosion?

Yes, I thought it was a duplicate initially. Ignore the comment above. Thanks.
