Powermock does not play well with java.time

From davidkar…@gmail.com on January 28, 2015 14:23:28

have this in a unit test which is annotated by: @RunWith(PowerMockRunner.class):

    LocalDate.now().minusYears(3).atStartOfDay().toInstant(ZoneOffset.UTC);

and it will blow up with:

teException: Failed to transform class with name com.davidkarlsen.traktorscrobbler.FileHandlingRouteBuilderTest.

I have similar issue on version 1.7.4:
