Mmmh, I can't login on reviewboard. my login works for svn.reviewboard.kde.org 
but not for git.reviewboard.kde.org...
I attach the patch here.

As for java parsing, the grammar caontains lots of conflicts. I don't really 
understand why but I believe it may be the source of some problems : not 
creating a DuChain because the Ast is almost empty (The only Ast node  given 
by the parser is a CompilationUnit (equivalent to the Start in the PHP 
plugin))

I don't really now how to start fixing that, I just started my Compiler course 
:)
