Holly Cummins resolved ARIES-845.
---------------------------------
Resolution: Fixed
Assignee: Holly Cummins
I've delivered a modified version of the patch which does the best it can to
allow the transaction wrapper to function on a Java 5 VM. I've disabled the
animal sniffer tests where required so that we can use the 1.0.0 parent pom.
> Support unwrap and isWrappedFor functions with older JDBC drivers in
> ConnectionWrapper

> ConnectionWrapper now simply delegates the unwrap and isWrappedFor functions
> to the wrapped connection. It would be good if we could be sure that the JDBC
> driver supports these functions as it is written in the javadoc. However in
> postgres 9.1 or H2 these functions are not supported and it is impossible to
> use api from that is supported by the vendor (e.g. LargeObject API from
> Postgres).
> A possible solutions is:
> In these functions we check first if the wrapped connection implements the
> queried interface. If not we delegate the function (thinking if we wrapped a
> wrapper it hopefully supports these functions).
