I’ve got a Java class which starts with

package examples.logging;

public class FastLogging {

    // Logging class

    public static native long logging_new(int level, String domain, boolean console, String file, String server,
            String connect, int max_size, int backlog);

    public static native void logging_set_level(long instance_ptr, int level);
...

When I run javac -h . examples/logging/FastLogging.java I get the following output:

/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class examples_logging_FastLogging */

#ifndef _Included_examples_logging_FastLogging
#define _Included_examples_logging_FastLogging
#ifdef __cplusplus
extern "C" {
#endif
/*
 * Class:     examples_logging_FastLogging
 * Method:    logging_new
 * Signature: (ILjava/lang/String;ZLjava/lang/String;Ljava/lang/String;Ljava/lang/String;II)J
 */
JNIEXPORT jlong JNICALL Java_examples_logging_FastLogging_logging_1new
  (JNIEnv *, jclass, jint, jstring, jboolean, jstring, jstring, jstring, jint, jint);

/*
 * Class:     examples_logging_FastLogging
 * Method:    logging_set_level
 * Signature: (JI)V
 */
JNIEXPORT void JNICALL Java_examples_logging_FastLogging_logging_1set_1level
  (JNIEnv *, jclass, jlong, jint);
...

How can I avoid that javac is inserting the “1” in the created function names, like Java_examples_logging_FastLogging_logging_1set_1level?
