Hello, We recently upgraded from Java 5 to Java 6 and found that our postgresql datasources were always trying to connect with the "sa" user name no matter what we put in the datasource. Putting the username and password in the JDBC URL in the datasource fixes the issue, but this is not normal. We've tried both 4.2.2 and the 4.2.3 compiled for Java 6 with the same results. Environment: java version "1.6.0_10" Java(TM) SE Runtime Environment (build 1.6.0_10-b33) Java HotSpot(TM) Server VM (build 11.0-b15, mixed mode) postgresql-8.3-603.jdbc4.jar postgresql server 8.3.4 What can I do to help track down the problem?
