Error after update 3.4.3 -> 3.4.4

[Robert Carnecky]

I updated Nitrite in my app from 3.4.3 to 3.4.4 (that's the only change I've made, no code changed) I now I get an error when accessing database , concrete on db.getRepository(My.class). When I revert back to 3.4.3 everything is ok. So for now I am sticky with 3.4.3.

What I did:

1. Close the database in the app with 3.4.3 on classpath, leave the app.
2. Start the app with 3.4.4 on classpath
   • open database is ok
   • db.getRepository() crashes with the following error - full errro stack follows

Looks like the problem is the new IndexMeta serialID! What have happened:

• the 3.4.3 database serialized data with a generated serial ID
• when I try to read read this data with the version 3.4.4 with another serial ID, I get the error and I can't use the old database anymore because the two classes do not have the same Serial ID and my program have no guarantee that the two serialized objects correspond to the same class format.

This is for me a breaking change!

Please stick to 3.4.3 version. 3.4.4 was released to fix the issue with generic serial UID. If you are creating new database, you can go with 3.4.4, otherwise stick to 3.4.3.
