If you look at the Java source for BitSet, you'll see it uses an array

"simulation" of long, but it's not perfect.

not likely the bit math would be correct without to

}
That way you don't pay for the

Are you sure the GWT long acts differently than a true Java long? My

I would because first of all you can check the code - this kind of stuff has

My assumption is, Async.RPC, like any static in a class, is not

Yeah, makes sense. I'd still do the log statement in the static initializer
just to be certain.
I don't see how any of this actually new though with 1.6. You could have
done all this earlier as well with the appropriate code snippet going into
the static block.

But it'll piss off your users
true, the static bloc is 10 LOC of boilerplate in 1.5/1.4
My app, has 20+ RPC interfaces, one per sub-system. They are all bound
to ONE RPC interface, the Server takes care of dispatching to the
right
POJO that matches the RemoteInterface dynamically. 1.6 was just less
boilerplate.

You can share code. The question of course becomes, shouldn't you extract
the common code & put it in it's own module. Then you can modify the module
descriptors to inherit the common module - that's the general way of
accomplishing this I believe.

It looks like you start your code in hosted mode, but then hit the page
using a regular browser. You cannot run HostedMode code against a regular
browser without the OOPHM plugin for obvious reasons. In HostedMode, your
code runs ins a regular JVM with GWT code that acts as a communication layer
Just a quick question. For such basic stuff, why are you using JSNI at
all? Just extend the widget to do what you want (or copy, paste & hack the
code from gwt).
This all seems to be something that is perfectly fine to be within the scope
of regular code.

You'd have to hack the source to force a locale. Or just change it so that

You are wrong. There is no .js file. This is true for (at least) all

Their demos might have used some js code.
