ReflectionException when EqualsVerifier fails to create PrefabValue for old Guava Range

[alastairandrew]

What steps will reproduce the problem?

Add an old version version of Google's Guava library to your classpath (13.0)

What is the code that triggers this problem?

Any EqualsVerifier usage.

Please try to provide an example of a complete class (equals method, hashCode method, relevant fields) and a call to EqualsVerifier.

What error message or stack trace does EqualsVerifier give?

What did you expect?

EqualsVerifier to only fail if the test actually used the old library.

Which version of EqualsVerifier are you using?

2.1.2
