JBossWrapper only checks directly wrapped objects in unwrap/isWrapperFor ------------------------------------------------------------------------ Key: JBJCA-952 URL: https://issues.jboss.org/browse/JBJCA-952 Project: IronJacamar Issue Type: Bug Components: JDBC Affects Versions: 1.0.14.Final, 1.1.0.Beta3 Reporter: James Livingston Assignee: Jesper Pedersen Fix For: 1.0.15.Final, 1.1.0.Beta4 The JavaDoc for the JDBC Wrapper class (http://docs.oracle.com/javase/6/docs/api/java/sql/Wrapper.html) says unwrap() should 1) return itself or a proxy when the reicever implements the interface 2) return the wrapped object or a proxy when the wrapped object implements the interface 3) call the wrapped object's unwrap() method if the receiver is a wrapper 4) other throw a SQL exception JBossWrapper only does 2 and 4. This means that is you have a WrappedConnectionJDK6 which wraps another wrapper which wraps OracleConnection, there you cannot get to the OracleConnection.
