What is libunsafe-mock-java
libunsafe-mock-java is:
sun.misc.Unsafe is Java class in Oracle JDKs that provides a collection of methods for performing low-level, unsafe operations.
Although the class and all methods are public, use of this class is limited because only trusted code can obtain instances of it.
unsafe-mock provides a current version of sun.misc.Unsafe that supports all APIs up through the new “fences” API in Java 8 EA builds b71 and later. This Unsafe is a copy of the one from Java 8 EA build b71, and it is expected that if you want to build against it you put it in javac’s bootclasspath. You are responsible for determining in your own code whether you can access Unsafe and which methods are available; this library is only to provide an all-inclusive Unsafe against which you can compile using JDKs <= 8.0.
