https://issues.apache.org/jira/browse/AMQ-3611 - Revert the Oracle jdbc adapter to a variant of the default jdbc adapter in place of the one supporting blobs. added oracleBlobJDBCAdapter for backward compatibility and latest oracle adapter extends the default adapter so it no longer manipulates blobs directly, works fine with the latest ojdbc6 driver
