Hi Oliver,

I think it would make sense to slightly clarify the documentation:

- Do not jump from inside a catch block and then re-throw the
exception in another execution context.
+ Do not jump from inside a catch block.

Otherwise it's a bit confusing because I don't re-throw exceptions in
my case but the problem is here.

Also, do you known whether it's safe to jump from inside of a try
block? I'm asking because there is a not at
https://docs.oracle.com/cd/E24457_01/html/E21991/bkahg.html that

> ... you must not longjmp into or out of a try-block or catch-block (directly or indirectly) ...
