Java erasure with generic overloading (not overriding)
I have FinanceRequests and CommisionTransactions in my domain. If I have a list of FinanceRequests each FinanceRequest could contain multiple CommisionTransactions that need to be clawed back. Dont worry how exactly that is done. The class below (very bottom) makes me feel all fuzzy and warm since its succint and reuses existing code nicely. One problem Type erasure. They both
