Thanks!

Greetings,

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 processAnnotationsJar
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!

Thanks!
