Powermock does not play well with java.time

[GoogleCodeExporter]

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. Reason: [source 
error] toInstant(java.time.ZoneOffset) not found in java.time.LocalDateTime

[GoogleCodeExporter]

I also tried it with javassist:
3.19.0-GA

[GoogleCodeExporter]

I have the exact same trace (except for the test-class, obviously).

Using mockito-core 1.10.19, powermock-api-mockito 1.6.2, 
powermock-module-junit4 1.6.2, javassist 3.19.0-GA.

Offending line of code: 
final Date start1415 =
            Date.from(LocalDateTime.of(2014, Month.AUGUST, 1, 0, 0, 0)
                .atZone(ZoneId.systemDefault()).toInstant());

[GoogleCodeExporter]

It looks like a bug in javassist.
see https://github.com/jboss-javassist/javassist/issues/43
You can reproduce this error without any powermock code.
