java.lang.NullPointerException

Hi, We are getting Java NLP while hitting 'back to results' link on almost all the business objects. Here is the stack trace. OTM version is 6.3.2 and this is a fresh installation. We couldnt replicate the same issue in other environments. Any help on this would be appreciated.
