I've run into this issue now myself, was there ever a resolution to this
or a workaround? As David said, supply an explicit value encoder isn't
able to solve the issue for me either.
Thanks,
Rich

In the past we have worked around the issue by providing an encoder
with our affected loops.
We are now working on upgrading from 5.1.0.5 to 5.2.4 and have run
into a new problem:
Even if we supply an encoder, the default encoder
(HibernateEntityValueEncoder) gets used and the NPE is back.
Below is a stack trace. Suggestions?
