extends java.lang.Object. The Assert class provides basic assertion and tracing support. All of the methods in this class are static and return void; this allows the OJC compiler to optionally exclude calls to these methods made from other classes. Thus, Assert method calls can be present in debug builds and not in release builds.

The synthetic field is generated so that Java only needs to call Assert.class.desiredAssertionStatus() once at load time, and it then caches the result there.
