  Mouse clicks not detected in JAVA after touching eGalax touchscreen

Status in “linux” package in Ubuntu:

Bug description:
  We have all-in-one PC terminal with touchscreen with Ubuntu 10.10 and
  JAVA application on Oracle JAVA JRE with some buttons. Working fine.

  After I did a minimal clean install from Ubuntu Server 12.04 CD (just with fluxbox WM) and Oracle JAVA JRE I run the JAVA application via javaws. I can click the buttons in the JAVA application using mouse, but when I try the same with touchscreen, the mouse pointer moves to the place I touched but the button is not pressed. After that when trying to use the mouse again even the mouse clicks are not detected !!!
  At first I thought it is the application problem but the same applies to the javaws laucher windows as well.

  Configuration of X11 in both versions of Ubuntu seems to be the same
  (no xorg.conf, just calibration.conf), no other adjustments.

  Touchscreen in Fluxbox is working fine in both versions. Since the
  JAVA version is the same in both versions of Ubuntu it cannot be
  problem of JAVA.

  To me it seems that in Ubuntu 12.04 the touchscreen/mouse events are
  passed to the JAVA VM differently than in Ubuntu 10.10.
