    @dkhwangbo Thank you for your work. But, asm module is a thirdparty package. So, we don't need to touch this source code. Instead, we should keep asm package using 1.7. For it, I'll add the following configuration in #778.
    
    ```
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <configuration>
              <source>1.7</source>
              <target>1.7</target>
            </configuration>
    ```

> Use of '_' as an identifier might not be supported in releases after java se 8. so, we must check code in whole project.
