"Absent Code attribute in method that is not native or abstract in class file"

[ab]

Dear All,

I'm trying to migrate from eclipse to glassfish at work but I'm experiencing some difficulties. The project context is a JEE web application based on glassfish 3.1.2 and JSF. The reason for migrating is that Eclipse is really slow when it comes to developping java classes and test it (build is still fast enough, but deploy is randomly slow, requiring many restart)

So then I tried Netbeans, which at first glance is well made for testing on glassfish. But... If the build runs correctly, the deploy always fails with the message "Absent Code attribute in method that is not native or abstract in class file", pointing a java classes that doesn't have any error. I have tried several actions: checkout a clean version of my current project from svn, import using the eclipse import assistant, try to configure netbeans to use the glassfish install I used with eclipse instead of the one provided... Nothing changes. I also tried to configure the project to add libraries (Java EE 6 API Library, Java EE from glassfish...).

So any hint on the way to investigate what the problem is or to solve it will be welcome.

Thanks

Alexis
