Subject Upgrade Groovy jar - can't start tomcat
Date Wed, 21 Mar 2018 11:01:37 GMT

I have been a happy user of groovy-2.3.7 for several years now on my tomcat
webapp under Java 8.  I just updated groovy-2.3.7.jar to groovy-2.4.14.jar
and now I am getting the following error:

Mar 21, 2018 5:47:07 AM org.apache.catalina.startup.ContextConfig
SEVERE: Unable to process Jar entry [module-info.class] from Jar
[jar:file:/.../build/web/WEB-INF/lib/groovy-2.4.14.jar!/] for annotations
org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte
tag in constant pool: 19

jar tvf groovy-2.4.14.jar    gives the expected list with no errors.  (I
think the jar file is fine.)

Sure appreciate any help!
