OK, I'll bite. Here's a way to make Method its own non-mutable encapsulation,
a la List::set or (future feature)

were introduced to do defensive copies (the sharing

Hi,
I was wondering if there is any reason for Method.copyOf (and friends)
being package private.
I'm trying to make a copy of a large number of Method objects in some
performance sensitive code to avoid sharing the isAccessible flag.
And while this is fairly fast.
Class declaringClass = method
