That's true for checked exceptions.  For unchecked errors, at least some of them,
the implementation has always had the right to move them around.
It would be reasonable, for example, for an implementation to vary in its choice
to wrap, or not to wrap, a stack overflow error, or out of memory error,
or thread-death, when passing through Method.invoke.  That's what
we are talking about.

That said, a very old API like jli.Method::invoke is going to have a lot
of folks placing a lot of unstated expectations on it.  But a relatively
new one like invokedynamic, which does not yet have a wide range
of use cases, can be changed without breaking many bits of code.
