JDBCRealm.getPassword throws NullPointerException

I'm using tomcat 5.5.20 with postgresql-8.1-407.jdbc3.jar and postgresql-8.1.4
on Ubuntu Dapper. Authenticating two users simultaneously with HTTP DIGEST
causes sometimes the following errors and a 401 Unauthorized reply:

Thanks for the report.

I have added the extra syncs required to fix this to SVN and the fix will be
included in 5.5.21 onwards.
