> Java 8 uses a different hash function for HashMap, which is leading to
> iteration order differences in several cases. (See
> [Java8|http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/8-b132/java/util/HashMap.java?av=f#336]
> vs
> [Java7|http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/7-b147/java/util/HashMap.java#HashMap.hash%28int%29])
> For example:
> - In Explain output: Stages are numbered differently
> - In PostExecutePrinter hook, table order is different in lineage.
