Invalid byte tag in constant pool: 19 error message

Question

This error message shows that the Tomcat is 8.0.30, and I am using JDK 8. I am creating a Spring-boot project. Some suggested that JDK 8 should be used but I indeed am using JDK 8. What's the problem here?

Answer 1

Tomcat 8.0 has reached End of Life and should not be used!

The replacement is Tomcat 8.5 (implementing the same specifications as Tomcat 8.0) or Tomcat 9.0 (newer versions of specifications). See "Migration Guide" at tomcat.apache.org.

org.apache.tomcat.util.bcel.classfile.Constant.readConstant(Constant.java:97)

The BCEL library here is used to parse class files when Tomcat scans for annotations. The version that you are using does not support some features in class file format of Java 8, and thus fails when trying to parse the file.

Your options:

1. Ignore.
2. Upgrade Tomcat.
3. Exclude those jars from annotation scanning. (See the official Tomcat FAQ → Performance → How do I make Tomcat start up faster?).
