RE: [eclipselink-users] com.ibm.ws.rsadapter.jdbc.WSJdbcConnectionincompatible with oracle.jdbc.OracleConnection

Please fail/reopen bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=225621

I have reported two WebSphere integration bugs inside. I think we should
test fixes before closing a bug.

oracle.jdbc.OracleConnection


The arguments to the getNativeConnection method are wrong, they must
include
WSJdbcConnection.class.  Please log a bug for this.
