Optimization of Map Queries

hi! I am having loads and loads of occurrences of something like ((com.test.MyEntity) $1.map.get('com.test.MyEntity')).someProperty ...

Unexpected Exception during commit

I'm testing code that otherwise has been working with a clean database. I have seen several examples of the following exception. It never seems to happen in the same place twice, though.
