Weirdness in native/jni/java-io/java_io_VMConsole.c

There's a very odd comment in this file: it clearly refers to some
method in another file.  But what was it for, anyway?  Surely the
name of a method and its signature is contained in the code.  I'd just
delete it.

/*
 * Class:     java_io_VMConsole
 * Method:    echo
 * Signature: (Z)Z
 */
JNIEXPORT jstring JNICALL
Java_java_io_VMConsole_readPassword (JNIEnv * env,
				     jclass clazz
				     __attribute__ ((__unused__)),
				     jobject con)
{
