> AsyncOpsTest, ChrootAsyncTest, and NioNettySuiteTest can fail running on Java
> 8 if child znodes are not added to a list in the same order as expected.

> FAILED
> expected:<OK:/foo:[child[1, child2]]> but was:<OK:/foo:[child[2, child1]]>

> This seems like a test only issue because getChildren javadoc says "The list
> of children returned is not sorted and no guarantee is provided as to its
> natural or lexical order." So, fix the tests by sorting the incoming lists.
