java.lang.NoSuchFieldError: INSTANCE

This is probably a dependency issue.

It's a very unclear error message but I found something similar here: Hibernate NoSuchFieldError INSTANCE but only with Struts 1?

I faced similar issue like this, In my class path there was two jar contains same class, httpcore-4.3 and apache-httpcomponents-httpcore, I have removed apache-httpcomponents-httpcore from class path solved the issue.
