The 1M data set is quite small so there should be no way it generates an out-of-memory error. I somehow suspect you are not actually setting MAVEN_OPTS in the same environment in which Maven is running. Or, you're not feeding the input you think you are or something. You would probably have to debug more on your side to understand it -- sounds like you're doing things right but can't be quite right.
