Hi DHIS2 Community,

I have been trying to upgrade to version 2.22 from version 2.20, however i
encounter an error in catalina.out. I have done what is advised on the
upgrade notes but still encounter an error.
The error is "SEVERE: Error deploying web application archive ROOT.war
org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte
tag in constant pool: 18"

Kindly assist as to where i may be wrong?

Charles.
