I am having an issue where I execute a single thread that
performs the exact same sequence of inputs every time. after several hundred successful runs, i get the exception below where
getHibernateLazyInitializer() can't be found:

i am using ehcache 1.2 on some entities for some very small amounts of reference data.
but the same problem is happenning with or without caching the entity.


Hibernate version: 3.1.3
