            The primary means for shifting computation is the condenser. A condenser is a component that transforms a program, yielding a program that is semantically equivalent under a stated set of constraints (e.g., “class X will not be redefined”), but may be smaller, faster, or better suited to a particular execution environment. Examples of possible transformations include replacing reflective calls with ldc instructions, generating dynamic proxies and lambda proxies ahead-of-time, propagating and folding constants, stripping dead code, and compiling to native code ahead-of-time; there are others. Some of these require no changes to the Java Platform Specification, whereas others will require additional specification support.
