Please CLOSE this bug report. It turns out that hashCode of a Hibernate proxy Collection was being called from my Entity's hashCode, resulting in the Exception.
In order to help avoid this sort of problem in the future, I've submitted an RFE with Lombok to help developers to reduce the boilerplate implementing the various different equals/hashCode patterns. https://github.com/peichhorn/lombok-pg/issues/115
