[ruby-core:65525] [ruby-trunk - Bug #10248] Possible missing test or bug for Module#include and Module#prepend

Issue #10248 has been updated by Timur Duehr.


I've created a patch to the MRI test suite used in JRuby to check for this behavior.

https://github.com/tduehr/jruby/commit/5bf0da4e4fff1a9e122ff427ff34586025db9955

I'm now using #9112 for discussion on new behavior with a patch to hopefully come before too long.

----------------------------------------
I've been implementing Module#prepend for JRuby. I ran into this test https://github.com/jruby/jruby/blob/master/test/jruby/test_method_cache.rb#L19

This was unexpected behavior for me. I've looked through both the MRI and rubyspec test cases and don't see a similar test.

If this behavior is intended, this test should be included in the suite. Currently, MRI passes this test for both include and prepend. When implementing include or prepend without referencing the MRI source code directly, the implementation won't necessarily pass this test.
