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