I have been using lombok (an annotation processor) for some time now, but yesterday suddenly it stopped working.

I get the following message:

Can't initialize javac processor due to (most likely) a class loader problem: java.lang.NoClassDefFoundError: Could not initialize class lombok.javac.handlers.HandleGetter

I do not know if this is related, but yesteday i for the first time since starting to use lombok, opened a text/html file in the editor. I suspect that this may have something to do with this, as it seems that an error like this one has been reported on the lombok site:

http://code.google.com/p/projectlombok/issues/detail?id=418


I reproduced the issue today in a new projectgroup, with a new java-maven project containing just one file that uses a lombok annotation, and it still fails.
Comment 1 Jan Lahoda 2013-02-15 12:11:36 UTC 
I have filled:
http://code.google.com/p/projectlombok/issues/detail?id=451

The problem is that NetBeans daily builds are now internally using javac from JDK8 for parsing, and lombok does not yet support it. I am afraid this cannot be solved on the NetBeans side.

(For the record, I think 418 is not related, that one might really be a classloading problem.)
Comment 2 Jan Lahoda 2013-02-15 12:13:58 UTC 
I forgot: I would suggest using NetBeans 7.3 until this is resolved.
Comment 3 akobberup 2013-02-15 12:27:25 UTC 
I see. Thanks for the explanation.

I have voted for the issue on lombok, and hope that they will soon update it.

I have been a glad user of dev builds for the past year now, but i guess that i will have to stop that for now and settle for a stable build.

Do you know in which dev build jdk 8 were introduced for javac internally? I have some installers lying in my download folder, so i can go back to the last one that were jdk7..

best
Anders
Comment 4 Jan Lahoda 2013-02-15 12:40:34 UTC 
The first with JDK8 javac is IIRC 201302130937, so the last one without it should be 201302122300.
Comment 5 akobberup 2013-02-15 12:48:05 UTC 
Thanks. Actually i were using 201302112300 yesterday - but i updated my plugins, and it must have thereafter that it went fubar :)

I will revert to 201302112300 without updating my plugins for now.

Comment 8 PavelCibulka 2013-10-11 13:12:03 UTC 
Project Lombok 1.12.2 has been released. This version should be working with NetBeans 7.4.

Maven:
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.12.2</version>
            <scope>provided</scope>
        </dependency>
Comment 9 rjdkolb 2013-10-11 13:15:38 UTC 
Hi Pavel

Checked this morning with 1.12.2.
Have not checked everything , but it seems to be working well on Netbeans 7.4RC2
thanks
Comment 10 Michel Graciano 2013-10-11 13:27:28 UTC 
We still have a regression when using this new version. Take a look at issue #236885.
