    This PR further improves the handling of Java 8 lambdas. It improves the handling of constructor
references. The following is now possible:
    `env.fromElements("xx", "xx").map(Trade::new).map(Trade::toString).print();`
    Unfortunately, I had to add the ASM dependency to `flink-core`. I hope this is not a problem.
