Problem while mocking javax.ws.rs.core.Request object with Mockito.mock(Request.class) #546

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
1. I have a simple test case mocking Request object which is a parameter to my 
REST endpoint call with @Context
2. I am mocking Request object as -> Request req = Mockito.mock(Request.class);
3. Passing in the Request object as an argument to my REST call within my test 
method

I am seeing exception failure as:
org.mockito.exceptions.base.MockitoException: 
ClassCastException occurred when creating the proxy.
You might experience classloading issues, disabling the Objenesis cache *might*

I am using mockito-all-1.8.4.jar and Windows 7 64 bits with Java 7

Am I mocking the request correct way or is it some calssloader issue as 
mentioned in the stacktrace ?
