Answer 1

There are couple of clues in the stack trace that point where the error is

a) ExceptionIninitializerError --> FormReferenceDataPopulatorTest. This indicates that the error happened during the construction of this object. The ExceptionIninitializerError specifically point to the fact that the exception occurred during static initialization block or variable

ExceptionIninitializerError An ExceptionIninitializerError is thrown to indicate that an exception occurred during evaluation of a static initializer or the initializer for a static variable.

b) Like Robby has pointed out in his comment Caused by: java.lang.RuntimeException: Could not locate bean of class [au.necdl.pexa.service.address.CountryService] shows where the error exact is.
