I have the problem with java instances not exiting after quitting minecraft. And I have K9 installed. I updated k9 and the problem is now fixed (the java processes associated with minecraft exit).
To update k9 I had to select in the K9 admin page: "Other settings" -> "Update to Beta". Then k9 was able to update to version 4.4.268 (seen under "k9 Update").
Without the Update to Beta option selected, k9 would not update to the 4.4.268 version.
