org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19

 

Invalid byte tag in constant pool : 19 는 19번 태그를 읽어올 수 없다는 내용이다.

19번 태그는 java version 9부터 지원하는 것이 보통이고 톰캣의 버전이 낮을때 주로 나타난다고 한다.

보통은 톰캣버전, 자바버전, lombok버전, log4j버전이 맞지 않을때 충돌로 인해 나타난다고 한다.

 

내가 발생한 케이스는 java 1.8 / log4j 2.17.1 / tomcat 8.5를 사용했을때 에러가 발생했다.

해결방법을 3가지 정도 찾았다.

1. 내 해결방법 : Tomcat version을 9이상 사용해서 해결했다.

2. 톰캣을 9.0이상 버전을 사용할 수 없다면  log4j 버전을 2.7로 사용하면 되는 경우가 있다고 한다.

3. 혹은 특이 케이스 이긴 하지만 jdk : 1.7.0 / tomcat 7.0.67 / lombok 1.16으로 해서 동작한다는 경우도 보았다.
