Why does `ScopedValue.where(SCOPE_VALUE, val).call()` throw Exception?

I know this is not the first (or last) discussion about functional
interfaces and checked exceptions.

But right now I'm using
try {
  return ScopedValue.where(S, value, callable);
} catch (RuntimeException e) {
  throw e;
} catch (Exception e) {
  throw new UndeclaredThrowableException(e);
}
everywhere. Because whatever the methods my callables are delegating to does
not throw any checked exceptions.

On the other hand, I could see myself calling MethodHandle.invoke/invokeExact
(throws Throwable) within a scope. Having only Runnable/Callable forces
me to do any error-handling within the scope itself instead of outside
of the scope.
