Server Timezone profile option at Site level is not set.

The Null Pointer Exception is occurring from within OA Framework’s code which Workflow’s code is calling.

iAS need to instantiate the class file and if it finds the profile to
be null it throws a null pointer exception. The JSP is then cached once
the profile is set afterwords and we will just be reading the cached
class. The error started occurring after making EBS timezone aware so
the profile need to be set to the timezone of the database to provide
the off set calculation for user connections. 


1. Set the profile option Server Timezone at Site level (should be set to the value of database timezone)
select DBTIMEZONE from dual;
2. Bounce the Apache Server
