On a cursory reading, it looks like a joke. All it seems to say is that they compile other languages into Javascript. There's tons of prior art involving compiling one high level language into another.
IANL, but I think everyone can just ignore this. It would never stand up in court.
That is not an issued patent, but rather an editited application. There is a good discussion of this on /. The consensus is that this will almost certainly NOT get approved, and that GWT is prior art (used internally at Google since 2004).
Like PG says, it would never stand up in court, even if the USPTO actually approved it.
