Incorrect mouse position in docked Java apps' context menu

[Trung Ngô]

Step to reproduce:

- Open BlueJ (http://www.bluej.org/)
- Right click in the main window, hover the mouse above that menu context
- Now dock the window to the left/right side of the screen
- Open the same context menu
- Hover the mouse again on that menu context

I attached a screencast showing the problem.

I've got the same problem with Pycharm IDE running OpenJDK 1.6 (6b27)
The issue seems relative to the JAVA JDK and Windows Manager name configuration.

SUN has fixed the problem by introducing Mutter as WM_NAME

The problem still remains here because WM_NAME is Gala.
The problem is fixed in Linux Mint.

They change the WN_NAME from Muffin to Mutter(Muffin)

Maybe we should consider to rename it ?

I just found a workaround by changing WM_NAME with wmname command.

Install the package suckless-tools :
sudo apt-get install suckless-tools

then use the command:
wmname Mutter

Launch you Java App.

Unfortunately it has to be done each time you restart Elementary.

#3 You should be able to set the command under Settings -> Startup programs to run after every boot.
