What steps will reproduce the problem? 1. Create the following classes:

public class SimpleOps
{
public List doStreamStuff(List inputs)
{
return inputs.stream().collect(Collectors.toList());
}
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(SimpleOps.class)
public class SimpleOpsTest
{
@test
public void testStream()
{
SimpleOps ops = new SimpleOps();
ops.doStreamStuff(Collections.emptyList());
}
}

1. Run the test What is the expected output? What do you see instead? I expect to see no output, just a passed test. Instead I see this Error:
   No methods matching the name(s) stream were found in the class hierarchy of class java.util.Collections$EmptyList.
   org.powermock.reflect.exceptions.MethodNotFoundException: No methods matching the name(s) stream were found in the class hierarchy of class java.util.Collections$EmptyList.
