DATASOURCE - Getting java.lang.NullPointerException

Configured a new 'DataSource' using oracle jdbc connection. It worked fine with less number of properties(automatically added ) when i configured through wizard. No issues with SQL query.

I deleted it and recreated with more properties ( 100+ fields ). When I validated the 'DataSource' i am getting the pop-up saying 'java.lang.NullPointerException'. No issues with test connection and the wizard also displayed first 10 rows.

Using latest version 3.6 of SoapUI PRO.

Here is what i want:

1) How do i generate the stack trace for this DataSource (or JDBC ?) issue alone ? This is the first step in my project. How do i go about troubleshooting this ?

Here is the content of error log taken from SoapUI:
