The file does not update when using "docker cp"

Question

The file does not update when using "docker cp"

I am trying to use docker cp to copy .class files from my host to a container. I use the following command:

docker cp foo.class container:/path/foo.class

I do this when the server running inside the container shuts down.

However, I see that foo.class is not updating with my last file, and if I try to execute the rm file, I get

 rm: cannot remove foo.class: Stale file handle

Here is my version of docker (Docker for Mac):
