/**
 * The <code>Compiler</code> class is provided to support 
 * Java-to-native-code compilers and related services. By design, the 
 * <code>Compiler</code> class does nothing; it serves as a 
 * placeholder for a JIT compiler implementation. 
 * <p>
 * When the Java Virtual Machine first starts, it determines if the 
 * system property <code>java.compiler</code> exists. (System 
 * properties are accessible through <code>getProperty</code>  and , 
 * a method defined by the <code>System</code> class.) If so, it is 
 * assumed to be the name of a library (with a platform-dependent 
 * exact location and type); the <code>loadLibrary</code> method in 
 * class <code>System</code> is called to load that library. If this 
 * loading succeeds, the function named 
 * <code>java_lang_Compiler_start()</code> in that library is called. 
 * <p>
 * If no compiler is available, these methods do nothing.
