Error jz00l when Connecting to sybase database via groovy

Hi, when I connect using the JDBC Request Test Step to my Sybase DB it works (or when I use the "test connection" button).

 

When I do the same via groovy it doesn't here is the code and the logs: 

I'm not sure if it's a driver problem (I have jconn4.jar in the bin\ext folder), it's not a credential problem. I'm using ReadyAPi 2.5.0 Pro

 

import groovy.sql.Sql

def ConObj = context.testCase.testSuite.project.databaseConnectionContainer.getResourceByName('TestAutomation');
def sql = Sql.newInstance(ConObj.getConnectionString());

Logs:

ERROR: java.sql.SQLException: JZ00L: Connection failed. Examine the SQLWarnings associated with this exception for the following reason (s):
