Spock framework throwing error while mocking a @component

Question

I am using Spock with Spring and I am getting error while mocking one of my component class.

Please find the below stack trace. It has nothing more than this and I thus I am not able to proceed. Versions:

• cglib-nodep : 3.2.0
• cglib : 3.2.0
• spock-core : 1.0-groovy-2.4

• spring-test : 4.1.4.RELEASE

Not sure why this happened but I just removed cglib and it just worked. So final dependency list was : cglib-nodep : 3.2.0 spock-core : 1.0-groovy-2.4 spring-test : 4.1.4.RELEASE

I am still not sure why this worked by removing cglib. In case someone has a detailed reason for this please share.
