I don't believe that exceptions raised in an exception block can be caught
by when clauses in that same block. You could do it with a nested block
like this though: -
BEGIN
BEGIN
<some code here - hopefully!>
EXCEPTION
WHEN exc_case1 THEN
<something specific>
RAISE exc_common;
WHEN exc_case2 THEN
<something different>
RAISE exc_common;
END;
EXCEPTION
WHEN exc_common THEN
<common exception code>
WHEN OTHERS THEN
<panic a little bit>
END;
