java.lang.VerifyError: incompatible argument to function

[Arun Thirupathi]

I am using Guice injection (version 4.0) for a personal project.

On one of my private methods (this method has nothing to do with Guice Injection, but consructor of this class uses Guice Injection) ,takes an argument of type com.amazonaws.AmazonWebServiceResult<ResponseMetadata> . The Caller passes in the object of type http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/dynamodbv2/model/QueryResult.html. It compiles fine, but during unit testing, it fails with an error

java.lang.VerifyError: (class: <className> , method: <methodName> signature: (L<Param1Class>;L<Param2Class>;Lcom/amazonaws/services/dynamodbv2/model/QueryResult;)Z) Incompatible argument to function

Is this a known Guice issue ?  

I tried moving this method to a new class (the new class does not have Guice Injection), tried adding one more intermediate method as pass through, but the error is still the same. But if the method parameter remains Result, if I extract the fields from the result and pass it down to another method it does not complain.

I was writing some generic code which could take in any result type and prints out the information like request id. I have added lots of duplication of code by defining one method per result type. Can someone please help me here ?

Thanks,

Arun.

That is a verification error thrown by the java reflection apis.  that implies that there is something wrong with the class file (and it just happens that guice is the first bit of code to notice).   Most likely your class file is simply corrupted

Is there any way to verify ? Also what is corrupted, the class I have or the amazon sdk jar ?

When I stop using the base class, it works well. Also other thing is I have 4 of these result types and I did a mix and match of the base class and it breaks if I have one of them. So it is hard for me to believe that class file is corrupted and this is not a Guice Issue.

I tried emptying the gradle cache, maven cache and rebuilding none of them works.

Thanks,

Arun.

if you call 'getDeclaredConstructors()' on that class (instead of having guice do it), does it work?  that would rule out guice as the culprit

Note that tests are failing. My test uses Mockito and PowerMock a lot, so could that be an issue ?

Let me prepend the call with getDeclardConstructors before guice injection and see if any of them fails and update this thread.

Thanks,

Arun.

Luke you are right. The reason I believe is this.
