Java security exception when trying to mock class: Signer information does not match signer information of other classes in the same package #427

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When I am trying to mock on of our classes, I am getting a Java security 
exception:

Caused by: java.lang.SecurityException: class 
"com.sun.jersey.spi.container.ContainerRequest$$EnhancerByMockitoWithCGLIB$$4748
8d7e_2"'s signer information does not match signer information of other classes 
in the same package

What puzzles me, is that I am using the same environment as on of my 
colleagues, who is NOT getting this exception.

Does anyone have an idea who we can solve this issue?

We are working with OSGi bundles (equinox), are using mockito version 1.8.4 and 
are running on Windows 7. Here is the call stack of the exception:

org.mockito.exceptions.base.MockitoException: 
Mockito cannot mock this class: class 
com.sun.jersey.spi.container.ContainerRequest
Mockito can only mock visible & non-final classes.
If you're not sure why you're getting this error, please report to the mailing 
list.

mmmh, signed package + osgi, we are unfortunately not experts on this, as we 
are not working in such environment. Do you have tried with a an updated 
version of mockito ?

If possible could you make us a reproducible test case ?

Cheers
