We have a number of JavaScriptObject subclasses. As I'm testing out
2.6.0-rc4, I'm getting an NPE from the compiler. (GWT 2.5.1 works without
any issue on our code base.)
I've attached a file with the full error, but here's an excerpt:

The particular class it's failing on has JSNI methods such as:
@Override
> public final native Manifest getManifest() /*-{
> return this.getManifest();
> }-*/;
All of these JSO classes implements interfaces, which the rest of our
application uses.
I rebuilt GWT and added a bit of debugging code. What I determined is that
on line 1999 of JsInliner, the "ref.getName()" is returning null. In that
same debugging code, I printed out "ref.toSource(true)" which shows this:
> this.getManifest
I also verified that "ref.getIdent()" is *not* null.
I'd be quite happy to add any more debugging statements necessary, apply
patches, whatever to get this fixed *before* 2.6.0 goes out for real.
FWIW, I've tried building a small sample app to demonstrate the issue, but
I have not yet been able to narrow it down. My quick attempt worked just
fine :-(
Thanks,
Jay
