According to javadoc comments:
 * 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.

 * If no compiler is available, these methods do nothing.

This doesn't seem to ve the case for methods
    public static native boolean compileClass(Class clazz);
    public static native boolean compileClasses(String string);
    public static native Object command(Object any);


e.g. compileClass method should return false if java.compiler property is not defined.
    /**
     * Compiles the specified class.
     *
     * @param clazz a class.
     * @return <code>true</code> if the compilation succeeded;
     * <code>false</code> if the compilation failed or no compiler
     * is available.
     */
    public static native boolean compileClass(Class clazz);

However these methods throw NullPointerException instead of returning false
if called with null parameter.

Here is a test:
======= CompilerTest.java =======
public class CompilerTest {

  public static void main(String[] args) {
    System.out.println(System.getProperty("java.compiler"));
    Compiler.compileClass(null);
  }

}
======= Output from the test =======
% java CompilerTest
null
java.lang.NullPointerException
at CompilerTest.main(CompilerTest.java:5)
