      Description

      Epsilon GC is the new experimental no-op garbage collector. Epsilon GC only handles memory allocation, and does not implement any memory reclamation mechanism. It is useful for performance testing, to contrast costs/benefits of other GCs. It can be used to conveniently assert memory footprint and memory pressure in tests. In extreme cases, it might be useful with very short lived jobs, where memory reclamation would happen at JVM termination, or getting the last-drop latency improvements in low-garbage applications. See more discussion about its use and tradeoffs in [JEP 318](http://openjdk.java.net/jeps/318).
