Hi Wido, Thanks for the reply and making a good point concerning Ubuntu 14.04.
Besides the difficulty in writing testes without increasing even more out technical dept, another point on the Java 8 platform is the EOL (end of this month) of Java 1.7. For now I created a ticket on Apache Jira to keep track of it: https://issues.apache.org/jira/browse/CLOUDSTACK-8397. Could you please have a look and let me know if the content of the ticket is appropriate? We will start a new sprint in 1 week and will take some time to discuss what to do and when. Will keep the community updated on that matter. Thanks a gain.

Why did I get stuck? The class used a few static methods that call native libraries, which I would like to mock. However, when writing the tests I faced problems with the current Mockito/PowerMock we are using: they are simply not enough for the task. What did I do then? I added a dependency to EasyMock and PowerMock-EasyMock API. It worked almost fine, but I had to add a “-noverify” to both my Eclipse Runtime configuration and also to the cloud-plugin-hypervisor-kvm/pom.xml file. I agree that’s not nice, but was my first attempt of getting it to work. After trying to first full build I faced more problems related to ClassDefNotFoundExpcetion which were complaining about Mockito classes. I then found out that adding the PowerMockRunner to all the tests classes was going to be a heavy burden and would also mess up future changes (e.g. the -noverify flag was removed from Java 8, thus adding it now would be a problem soon). Now that the first 2 paragraphs explain a bit about the problem, let’s get to the solution: Java 8 The VerifyError that I was getting was due to the use of the latest EasyMock release (3.3.1). I tried to downgrade it to 3.1/3.2 but it also did not work. My decision: do not refactor if the proper tests cannot be added. This left me with one action: migrate to Java 8. There were mentions about Java 8 in february[1] and now I will put some energy in making it happen. What is your opinion on it? I'm not against it technically, but practically I am. Ubuntu 14.04 does not ship a Java 8 JRE in the repositories. CentOS 7 has java-1.8.0-openjdk.x86_64 available, so it would work there. But Ubuntu is also widely used with CloudStack, so those users couldn't use CloudStack without any additional repositories. Since that isn't easy I would vote -1 on this if it came that far. Wido Thanks in advance.
