the problem started when added following start of test suite:

@runwith(powermockrunner.class) @preparefortest({problemclass.class, classbeingtested.class})

with goal being when class being tested attempts instantiate problemclass, it'll create mock object instead of real instance.

the classbeingtested extends class that's mentioned in stack trade. i.e. classbeingtested extends [class name].

i spying on implementation of classbeingtested, method nothing when called rather being called.

i'm not sure if prehaps there kind of interference it's not ok both prepare class test , insert mocked constructor in there as as spy on it?

note: can run tests fine in intellij using either run/debug. in both cases test completes , shown passing. it's when ant build occurs fails.
