Selenium script stuck on driver.get after JRE upgrade

I have a Selenium script which logs into the application and performs checks. This script has been running fine for over 6months.

Couple of weeks ago, we had a minor JRE upgrade(1.7 Update 11 to 13) on the server where we run the scripts using Jenkins scheduler, Since then the script waits on driver.get and just does not proceed. I was able to reproduce the issue on the server when run using the UI as well.

The script does not fail and neither does it throw any error, it just halts there forever. Unable to decipher what is happening here.

Any thoughts?
