TypeNotPresentExceptionProxy

Question

When upgrading from Surefire 2.6 to Surefire 2.13, I get a TypeNotPresentExceptionProxy when running my unit tests.

java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy
    at sun.reflect.annotation.AnnotationParser.parseClassArray(AnnotationParser.java:653)
    at sun.reflect.annotation.AnnotationParser.parseArray(AnnotationParser.java:460)

    at java.lang.Class.getAnnotation(Class.java:3029)
    at org.apache.maven.surefire.common.junit4.JUnit4TestChecker.isValidJUnit4Test(JUnit4TestChecker.java:64)

In JUnit4TestChecker, line 64 looks like this:

Annotation runWithAnnotation = testClass.getAnnotation( runWith );

So Surefire inspects the @RunWith annotation to make sure its type is valid. Our tests use Spring, so @RunWith looks like this in our test classes:

@RunWith(SpringJUnit4ClassRunner.class)

It seems like Surefire isn't finding the SpringJUnit4ClassRunner class. I'm not sure why since under Surefire 2.6, the tests run fine.

Any ideas?

Run mvn dependency:resolve

Exclude any 3.x version of JUnit that may have crept in.

Make sure there are no TestNG dependencies, if there are it will load TestNG annotations and not the JUnit ones you need.
