這個是Tomcat的BUG https://bz.apache.org/bugzilla/show_bug.cgi?id=60688 https://stackoverflow.com/questions/23541532/org-apache-tomcat-util-bcel-classfile-classformatexception-invalid-byte-tag-in

This was a Tomcat bug that resurfaced again with the Java 9 bytecode. The exact versions which fix this (for both Java 8/9 bytecode) are:

• trunk for 9.0.0.M18 onwards
• 8.5.x for 8.5.12 onwards
• 8.0.x for 8.0.42 onwards
• 7.0.x for 7.0.76 onwards
