Knut Anders Hatlen updated DERBY-2328:
--------------------------------------
Attachment: unused.diff
LanguageConnectionContext has a method called getLockSpace(int) which creates a
compatibility space, but the method is not used. unused.diff removes the method
so that it doesn't complicate things when the use of compatibility space
objects changes. All the tests passed.
