NullPointerException hides cause of PostgreSql Exception for getConnection call. -------------------------------------------------------------------------------- Key: JBJCA-1264 URL: https://issues.jboss.org/browse/JBJCA-1264 Project: IronJacamar Issue Type: Bug Components: Core Affects Versions: 1.0.30.Final Environment: All environments. Reporter: Jeremy Whiting Assignee: Jesper Pedersen Labels: nullPointerException, pgsqlexception When a datasource using PostgreSql is configured with the "loglevel" property the JCA db server causes a PGSqlException. Besides that cause the exception is not displayed to the user. org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections. The JCA code attempts to handle the exception in a catch block. Initially by logging a message. But the JCA code to log the message assumes the clw reference is not null. On this line https://github.com/ironjacamar/ironjacamar/blob/ironjacamar-1.0.30.Final/... In my case clw is null. Which then causes an NullPointerException. Completely hiding the underlying exception to the user.
