NullPointerException occurs when I try to access a lazy-loading field on non-existent entity outside the transaction (ENABLE_LAZY_LOAD_NO_TRANS=true). As the result, I get LazyInitializationException with null message. If the same is done inside the transaction then the correct exception will be thrown (ObjectNotFoundException) and the correct message will be given (No row with the given identifier exists).

I made github PR with a test and a possible fix.
