What steps will reproduce the problem? 1. Surround a method, which throws multiple checked exceptions, with a try catch block
2. Collapse all exceptions in 1 line of code. For example, when using reflection to call a method, it will throw several checked exceptions, like this:

try {
Class<? extends ControlledVocabulary> entityClass = findControlledVocabularyFor(request.getType()).getEntityClass();
builder = (ControlledVocabulary.Builder) entityClass.getDeclaredMethod("builder").invoke(null);
} catch (IllegalAccessException | NoSuchMethodException | InvocationTargetException e) {
LOGGER.error(TAG, "Could not instantiate ControlledVocabulary of type " + request.getType(), e);
throw new RuntimeException("Could not instantiate ControlledVocabulary of type " + request.getType(), e);
}

(ignore the business rules behind this, let's just say that I'm getting some class, based on a string in the request, and I am calling a (static) method to get a builder object from that class)

1. Write a unit test for this class using PowerMock. For testing reasons, I had to mock a constructor used by that class. So, annotated on the type are these annotations:

@RunWith(PowerMockRunner.class)
@PrepareForTest(ManageControlledVocabularyService.class)

... where, evidently, ManageControlledVocabularyService is the class which I'm testing.

############################ What is the expected output? What do you see instead? I would expect PowerMock not to complain :-)

Instead, I get a java.lang.VerifyError:
