@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>
```
> Remove '_' as an identifier

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