What steps will reproduce the problem?
Not quite sure. It seems to be related to highlighting occurrences, but doesn't always occur. I could sometimes reproduce it by using F3 to go view a library call:

1. Have a source file that calls a library.
2. Use F3 to open the library file (make sure it isn't open already) to view the code for that call.
3. Popup happens

What version of the product are you using? On what operating system?
Lombok 1.14.2 and 1.14.4
Eclipse 4.3
Java 1.7.0_40
Windows 7

Please provide any additional information below.
I've seen this happen with 2 different stacktraces in the error log. Both reference the same Lombok class, but no other Lombok code.

I've just seen this happen with Lombok 1.14.8 in Eclipse 4.4.0 on Java 1.8.0_25 as well.

Would you like to test using the edge release? It is experimental, but uses a different class loader infrastructure: https://projectlombok.org/download-edge.html

Do you have a reproduction recipe?

I've also seen the issue (or similar) with:
Lombok 1.14.8
Eclipse 4.4.0
Java 1.7.0_05
Scientific Linux 6.4

For me, it happened when I opened an editor for a Java class that didn't even use Lombok. I had multiple projects in my workspace, however, and a different project does use Lombok.

Issue #798 has been merged into this issue.

👤 shawn.tuatara   🕗 Feb 08, 2015 at 02:02 UTC

The comment in ﹟763 about toggling the mark occurrences fixed this issue temporarily for me. Would be nice to have this issue resolved as that is an important feature to see into the code better.

Lombok: 1.16.0
Eclipse: STS 3.6.3

👤 reinierz   🕗 Apr 14, 2015 at 20:46 UTC

This may have been fixed in the latest release of lombok (v1.16.4); give it a shot?

[lombokissues]

👤 igor.berman   🕗 Jul 08, 2015 at 06:12 UTC

I think, 1.16.4 fixed the problem

[lombokissues]

End of migration

[msimko81]

Having the same problem with 1.16.6.
The error occur when using 'val' type but is not always reproducible even on the same file after several eclipse restarts.
No message inside workbench error log, just the following popup window:

An internal error occurred during: "Requesting Java AST from selection".loader (instance of lombok/launch/ShadowClassLoader): attempted duplicate class definition for name: "lombok/launch/PatchFixesHider$PatchFixes"

[caarlos0]

Same here

[tungpham]

Same for me as well.

[rzwitserloot]

The duplicate class def thing is a different error entirely, it just so happens to also manifest as a LinkageError; the last 3 comments above this one all reference it. I've made issue #1293 to reflect these new ones. I'm going to consider the original fixed.
