Thanks! Question - is there a way to fetch the current Throwable from
within a finally clause?

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.
