I recently started seeing "java" processes with the default Java icon sometimes stay in the switcher/dock after Java Web Start applications are closed (OS X 10.9.5 Mavericks). This may have begun with JDK 1.7.0_76-b13.
pgrep java shows there are no such processes. Force Quit does not work and they do not appear in the Activity Monitor.
I am behind corporate firewall/anti-virus and only use Java for local, proprietary applications. The disk has been verified by Disk Utility.
So far I have found that
killall -KILL Dock will get rid of most of them but often leaves at least one called "java" with the command-line icon (black terminal window with green "exec" writing). Example from the Dock:
Does anyone else experience this or know - more generally - the cause and workaround?
