Handling String date format "0000-00-00 00:00:00" removed in latest version???

I recently tried upgrading to connector/J 3.1.6 - only to find this immediately broke my application wherever I was using zero dates in string format "0000-00-00 00:00:00".

The connector/J changelog states that there are now three ways of handling zero dates, the default now being 'exception', and that other methods of handling can be specified in the server.xml connection url. This enabled me to correct the initial errors with zero dates.

HOWEVER even if I change my server.xml, change all my zero dates to the supposedly valid "0001-01-01 01:01:01" (or "0001-01-01 00:00:00" I tried both) and change all (PreparedStatement) queries to reflect this, the MySql server dies a death as soon as I try to execute a query that references the date field
(select ... where date='0001-01-01 01:01:01').

The error (repeated - for each row in resultset?):
______________________________________
Communications link failure due to underlying exception:

** BEGIN NESTED EXCEPTION **

java.net.SocketException
MESSAGE: Connection reset

STACKTRACE:

java.net.SocketException: Connection reset
______________________________________

The errors occur identically on two installations - one running under Tomcat 5.0 and one Tomcat 5.5.7.

I have reverted to connector/J 3.0.11 for now which works fine, but if anyone knows a way round this, it would help. I'm very surprised indeed that 3.1.6 is not backwards-compatible? - guess I'll be sticking with 3.0.11 unless something changes.
