Release 3.0: additional Java changes

There are several additional types of exceptions thrown in the Berkeley DB 3.0 Java API.

DbMemoryException and DbDeadlockException can be caught independently of DbException if you want to do special handling for these kinds of errors. Since they are subclassed from DbException, a try block that catches DbException will catch these also, so code is not required to change. The catch clause for these new exceptions should appear before the catch clause for DbException.

You will need to add a catch clause for java.io.FileNotFoundException, since that can be thrown by the Db.open and DbEnv.open functions.

There are a number of smaller changes to the API that bring the C, C++ and Java APIs much closer in terms of functionality and usage. Please refer to the pages for upgrading C applications for further details.
