Something You Should know

this tool is designed for projects built on maven & junit
ensure surefire plugin is in your project
for jdk 1.7 and jdk 1.8 and after, you should add extra jvm args to skip stackmap check
- for jdk1.7( -XX:-UseSplitVerifier )
- for jdk1.8( -noverify )
- or you could add them both

   <!-- for jdk 1.8 and after-->
   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <version>3.0.0-M5</version>
       <configuration>
            <argLine>-noverify</argLine>
       </configuration>
   </plugin>
   
   <!-- for jdk 1.7 -->
   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <version>3.0.0-M5</version>
       <configuration>
            <argLine>-XX:-UseSplitVerifier</argLine>
