I am using cobertura-maven-plugin-2.7 and I am getting an error when I do a maven build.

But when I run the Junit test case independently it is successfully executed.

Environment:

Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T12:37:52-05:00) Java version: 1.8.0_51, 
vendor: Oracle Corporation Java home: F:\Java\JDK8_51\jre Default locale: en_US, 
platform encoding: Cp1252 OS name: "windows 7", 
version: "6.1", 
arch: "amd64", 
family: "dos" Junit 4.12

        .getLogger(CustomClass.class);

UPDATE:

Hi.Thanks I did make some changes to code to remove the "static" references which are not needed.But I still have issues in mocking any of the interfaces which work fine if I run individually using Junit but fail when I do a build using cobertura.Any inputs please? Sorry for not posting another question as the issue of not able to build using cobertura 2.7 still persists but in another form.

You might have run into a bug: Instrumented classes throw NPE during static initialization.
