Please describe the expected behavior of the issue

I expect to be able to mock such a class and do all the normal mock-related operations.

Please provide a description of what actually happens

I am trying to mock the FileStatus class (source code here) from the Hadoop common API Java library. The following compiler errors result:

Error:(34, 24) double definition:
override def compareTo(o: Any): Int at line 34 and
override def compareTo(x$1: T): Int at line 34
have same type after erasure: (o: Object)Int
    val mockFile = stub[MockFileStatus]
Error:(34, 24) name clash between defined and inherited member:
def compareTo(x$1: T): Int in trait Comparable and
override def compareTo(o: Any): Int at line 34
have same type after erasure: (x$1: Object)Int
    val mockFile = stub[MockFileStatus]

The problem seems to be with the fact that this class extends Comparable without specifying any type parameters.

Any workarounds (however ugly) are welcomed. Thank you.

Reproducible Test Case

Note: you will need to add a dependency on hadoop-common 2.6.5.

test("my failing test") {
  // your imports
  import org.apache.hadoop.fs.FileStatus
  // code that fails
  val mockFile = mock[FileStatus]
}

My apologies; I thought this was a similar case to #86, which had some discussion, but I guess it's not. Will post to SO instead.
