Powermock cannot handle collapsed catch blocks (introduced in Java 7) #485

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
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)

3. 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:

<<<END FULL STACK TRACE>>>
-----------------------------------------------------

What version of the product are you using? On what operating system?

PowerMock version: 1.5.4
Mockito version: 1.9.5

Please provide any additional information below.

There are 2 workarounds for this problem: 
(1) Uncollapse all the exceptions. That means: revert to the Java 6 situation. 
Lesser of many evils, but it does not use the Java 7 capabilities, which leads 
to more code. And in my case: reproduction of code. 
(2) Don't catch multiple exceptions, just catch (Exception e): Worst of many 
evils, in my book. Not only will I catch other exceptions (if any), which do 
not belong to the code I'm executing; you'll also loose the concept of catching 
a single type of exception. But you could also state that if you collapse all 
the exceptions, you're not interested in a single type of exception, which 
would not be a wrong assessment, I guess.

Haven't retried, but I don't think so, given the status of the ticket ...

I saw this issue disappear after updating to javassist-3.19.0 (along with 
powermock-easymock-1.6.0).
