Document this in Release Notes or better in Messaging User Guide: "Oracle JDBC driver version 11.1.0.7.0 causes the JBoss Messaging Test Suite to fail with a SQLException ("Bigger type length than Maximum") on Oracle 11g R1. This is caused by a regression in Oracle JDBC driver 11.1.0.7.0. We recommend Oracle JDBC driver version 11.2.0.1.0 for use with Oracle 11g R1, Oracle 11g R2, Oracle RAC 11g R1 and Oracle RAC 11g R2. "
Correction document just this note: "Oracle JDBC driver version 11.1.0.7.0 causes the JBoss Messaging Test Suite to fail with a SQLException ("Bigger type length than Maximum") on Oracle 11g R1. This is caused by a regression in Oracle JDBC driver 11.1.0.7.0." At this moment it's not clear whether newer driver 11.2.0.4.0 fixes this problem.
