Looks like the field has been renamed to just "testClass" in JUnit 4.12.

This should be changed to High priority since there is no way to run PowerMock 
with JUnit 4.12.

Also, changing to JUnit 4.11 to workaround this problem causes another problem:
org.powermock.reflect.exceptions.FieldNotFoundException: No instance field 
named "fAnnotations" could be found in the class hierarchy of 
org.junit.runner.Description.

In https://github.com/junit-team/junit/releases, the version is 4.12-SNAPSHOT. 
Hence the fix 
static {
        if(JUnitVersion.isGreaterThanOrEqualTo("4.12")) {
            TEST_CLASS_FIELD = "testClass";
            CLASS_UNDER_TEST_FIELD = "klass";
            ERRORS_FIELD = "errors";
        }
        else {
            TEST_CLASS_FIELD = "fTestClass";
            CLASS_UNDER_TEST_FIELD = "fClass";
            ERRORS_FIELD = "fErrors";
        }
    }
doesn't apply to this version as JUnitVersion.isGreaterThanOrEqualTo("4.12") 
gives false in this case.
