Hi,

Seems that you are using JaCoCo version 0.6.3 , while support for Java 8 was added in later versions - see http://www.eclemma.org/jacoco/trunk/doc/changes.html Please upgrade to most recent one, which is 0.7.5 - http://www.jacoco.org/jacoco/index.html

Hi Evgeny,
Actually I used version 0.7.5.
After switching to 0.7.6 snapshot issue solved.

[Henrik Horneber]

Just as a different view on this:

We had the same issue, but using jacoco 0.7.5 resolved it.

Also, org.jacoco.agent.rt.internal_9dd1198 very much looks like 0.6.x.

regards,

Henrik

amiraf, I doubt that you used "0.7.5" - I double checked that "org.jacoco.agent.rt.internal_9dd1198" is from 0.6.3, so agree with Henrik. If issue is solved, then fine, but keep in mind that preferable to use released version than snapshot.
