 * The {@code Compiler} class is provided to support Java-to-native-code

 * nothing; it serves as a placeholder for a JIT compiler implementation.
 * If no compiler is available, these methods do nothing.
 *
 * @deprecated JIT compilers and their technologies vary too widely to
 * be controlled effectively by a standardized interface. As such, many
 * JIT compiler implementations ignore this interface, and are instead
 * controllable by implementation-specific mechanisms such as command-line
 * options. This class is subject to removal in a future version of Java SE.
