Re: JSO: Why does this fail?

OK, I understood (which actually I find scary).

Thanks!

So the answer to

When use it ? When not use it ?

is respectively always and never ? That's easy to follow, thanks!

Hmm, no. If your JSNI calls back into Java "synchronously", then you don't need to use $entry (exceptions will still "bubble" up to your GWT.UncaughtExceptionHandler Java→JSNI→Java, and you're still in the same event-loop wrt scheduled commands). You use $entry() whenever the browser calls back into your GWT/Java code "asynchronously" (event handling, promises, etc. basically whatever comes from the browser's own event loop).

Basically, whenever you pass a "callback" to be called "later", decorate it with $entry().
