I updated schema and improved code to make it properly compare JIDs. I executed tests for each DB schema and all tests for DAO implementation are passing for every database.

I also update ACS for PubSub to make it work with updated version of PubSub component.

Looks good!

I would only explicitly define Unicode character encoding in byte[] hash = md.digest(data.toLowerCase().getBytes()); in Derby SPs.

Andrzej, as this is a new schema version, after making changes please assign ticket to Daniel so he can update documentation with the correct schema version ( %daniel , this is applicable to the upcomming 7.2.x version, i.e. origin/master branch )

%wojtek I replaced usage of getBytes() with getBytes(UTF8) in each implementation of StoredProcedures class including also implementations from MUC, Tigase Server, MA and MUC. Additionally I did same change to functions used in Tigase Mongo project for hashing JIDs.

Added notation to documentation of pubsub upgrade.
