14.16 is right to say that:
A break statement with value Expression ***attempts to cause the
evaluation of the immediately enclosing switch expression***
to complete normally ...
because the following is legal (x will become 200) :
int x = switch (e) {
case 1 -> {
try { break 100; } finally { break 200; }
}
default -> 0;
};
Therefore, in the discussion section, please say that:
The preceding descriptions say "attempts to transfer control"
***and "attempts to cause evaluation to complete normally",***
rather than just "transfers control" ***and "causes evaluation
to complete normally",*** because if there are any try statements ...
... innermost to outermost, before control is transferred to the
break target ***or evaluation of the break target completes***.
[Notice we don't yet know if evaluation of the break target
will complete normally or abruptly. If the finally clause above
was to throw an exception instead of break-200, then the
switch expression would complete abruptly by reason of the
exception, rather than completing normally with the value 100.]
(Separately: Please flag the new text in 15.15's opening line.)
