Description

This is a follow-up to ARIES-1171.

aries-transaction-jdbc can wrap a "normal" DataSource with pooling functionality. If that happens, it calls DataSource.getConnection(String, String) with null user/password (in case aries.xa.username and/or aries.xa.password are not set.

In some DataSource-implementations this causes a NPE, e. g. DB2. Derby and H2 for example also work with null parameters.

A fix similar to ARIES-1171 is proposed.
