Powermock does not play well with java.time

[johanhaleby]

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

[johanhaleby]

From davidkar...@gmail.com on January 28, 2015 05:24:21

I also tried it with javassist:
3.19.0-GA

[johanhaleby]

From buurman....@gmail.com on April 28, 2015 01:55:05

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());

[johanhaleby]

From andreas....@web.de on May 23, 2015 06:11:43

It looks like a bug in javassist.
see jboss-javassist/javassist#43 You can reproduce this error without any powermock code.

[gigaSproule]

This is no longer an issue as of 1.6.6 (possibly earlier, but I've just tried 1.6.6 after it failing in 1.6.1)

[thekingn0thing]

@gigaSproule, than you for letting us know about it. So I closed the issue as resolve.

[ashwanikumarindian]

Still facing the issue with version 1.6.6 and 1.7.1
Date t = new Date(YearMonth.now().atStartOfDay().atZone(ZoneId.systemDefault()).toInstant().toEpochMilli());

OR

Instant instant = monthStartDateTime.atZone(ZoneId.systemDefault()).toInstant();

Fixed 👍
After swtiching to:

• latest javassist version: 3.23.0-GA
• powermockito version: 1.7.1

Was there anything else you had to do? I switched my dependencies to those versions and I'm still seeing the same error.

[rcoelho6]

I have similar issue on version 1.7.4:

Code:
ZonedDateTime zonedDate = Instant.now().atZone(ZoneOffset.systemDefault()).withHour(14).withMinute(0).withSecond(0); Instant baseInstant = zonedDate.toInstant();
