Description

Since 2.5, groovy is provided through modules only (the groovy-all jar has been removed) 

The core module is groovy.jar, then additional modules like groovy-json are osgi fragment.

Currently these cannot be really used in eclipse target platform, because classes exported by fragment are not visible by PDE. 

Adding Eclipse-ExtensibleAPI: true to the groovy.jar manifest would solve that issue. This header is only used by PDE, it has no impact on osgi runtime.
