Raw type fixing is not part of this PR, I would like to do that separately as it will be more involved (when fixing a raw type, usually other warnings pop up, like unnecessary casts or unchecked warnings).

I can reproduce this. This looks like a bug in the Eclipse compiler.  The Eclipse Compiler is incremental and may not be recompiling the correct sources affected, but on a full rebuild it does.  It should probably be reported if it can be narrowed down a bit.
