Simone Tripodi updated DBUTILS-96:
----------------------------------
Attachment: DBUTILS-96_v2.patch
A new small patch where added a guard for {{ClassCastException}} to return
{{false}} when happens.
Moreover I renamed the {{DriverAdapter}} to {{DriverProxy}}, sounds more
reasonable.
{{TODO}}: I am still not able to manage the {{IllegalAccessException}}...
> dynamic load jdbc jars use Dbutils,it say No suitable driver found for jdbc
