Tomcat 7 Gets Errors During Startup of Java Project

Question

I have a Java project which was working perfectly before. Now I'm getting the errors below. The server startup is successful but the services do not work. Java version of the project is 8 and I use Tomcat 7 server.

@jan.supol I've changed the version of ASM but still getting the same error. — esdoodle, Jun 27 '20 at 11:23
The exception says you have byte code of version > 1.8. How is that possible? — jan.supol, Jun 29 '20 at 09:00
@jan.supol The exception is thrown in a class of jersey bundle but I don't really understand the reason — esdoodle, Jun 29 '20 at 18:55
Jersey inspects resource classes using the ASM, so that it knows what methods to invoke upon http request. The ASM says that resource class has byte code of JDK > 1.8 — jan.supol, Jun 30 '20 at 20:55
