As suggested in the error message, I set openjpa.Multithreaded property to true 
as a workaround. But this may slow down the site speed according to the OpenJPA 
manual.

>> excerpted from OpenJPA manual:

OpenJPA respects the openjpa.Multithreaded option in that it does not impose as 
much synchronization
overhead for applications that do not set this value to true. If your 
application is guaranteed
to only use single-threaded access to OpenJPA resources and persistent objects, 
leaving this option
as false will reduce synchronization overhead, and may result in a modest 
performance increase.
