I found different possibilities to open Windows applications minimized from cmd.exe. Best related topics I found were: open program minimized via command prompt and Run Java console app as a daemon (background)
What I couln'd get working is running a .jar from cmd in a minimized or background state. The window still pops up in front with, e.g. :
START /min javaw -jar App.jar &
or
START javaw -jar App.jar --new-window/min
or other variations of these cmd options.
I made a workaround by setting it up in the application itself with frame.setState(Frame.ICONIFIED)
But does anyone know how to do this by cmd, or what could be the problem (Win7 x64)?
