just(T) : RxJavaObservableExecutionHook not called

[ronanM]

When using rx.Observable.just(T) the RxJavaObservableExecutionHook is not call.

This is not like other just(T,...) that call rx.Observable.from(Iterable<? extends T>).

Thanks for the report.

@abersnaze Since this probably affects work you're doing as well, can you take a look at what we need to fix here? It will be anything using the internal ScalarSynchronousObservable optimization I think.

[abersnaze]

sure.

What is the status of this issue? I've lost track of the proposed changes to ScalarSynchronousObservable.

See #3958.
