Thanks! Question - is there a way to fetch the current Throwable from
within a finally clause?
Andrei
I'm pretty sure you can't since finally isn't passed an exception. I
also don't see anything in my quick search.
That stands to reason because in some cases (when things go
correctly) there isn't one.
One hopes. Just the same: (hypothetical syntax incoming)
try {
// ...
}
catch ( ExceptionA exa ) {
// ...
}
catch ( ExceptionB exb ) {
// ...
}
finally ( x ) {
// ...
if ( x ) throw new ExceptionC( x );
}
And obviously if finally has no () it doesn't bother with the feature.

I'm not that fancy. An API call getCurrentError returning an Error
object or null is all that's needed. And more general too.
Andrei
At which point one could argue that the constructor of Throwable or Exception could/should
call that same API function itself. I'm not strictly opposed to it, mind you, it just
bodes ill not to thoroughly examine such auto-magic.
