Issue with Powermock using jacoco code coverage

[ghr...@gmail.com]

Hi ,

I am getting an error is already instrumented while using jacoco code coverage using maven. My project is maven project.It has maven dependencies powermock, mockitto and jacoco plugin.
I believe it is causing error "default-restore-instrumented-classes". If I remove this it is not generating jacoco coverage report.
When I run mvn clenn install, the build is working fine and generating jacoco coverage report. But in console it is generating huge exceptions already instrumented

Hi,

you cannot combine offline instrumentation with the JaCoCo agent. This
results in classes getting instrumented twice. See documentation

http://eclemma.org/jacoco/trunk/doc/offline.html

and our example project here:
