A couple of peculiarities in the study that place Java at a disadvantage:

1. Examples using outdated low level concurrency primitives such as wait and notify. Use of java.util.concurrent would have made the code much more terse and safe

2. Java performance affected by use of the outdated java.util.Stack class. It is well known that this class uses redundant synchronization. The docs recommend using a Deque implementation instead.
