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
<http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/AmazonWebServiceResult.html>
<ResponseMetadata
<http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/ResponseMetadata.html>>
. 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.
