JDK-8130227 - JEP 274: Enhanced Method Handles
Description
private static void target() {}
private static void cleanup(Throwable t, int a1) {}

Calling tryFinally on these leads to "IndexOutOfBoundsException: toIndex = 1", when I expected to get IllegalArgumentException.
I think IllegalArgumentException description is OK, but the javadoc misses IndexOutOfBoundsException description.
Comments
The problem here is that a too short parameter type list in the target is not taken into account properly. The exception thrown should be an IAE.
