Same problem here under Linux Debian 64 bit with this Java Installation:
>>> java -version
java version "1.7.0_95"
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb8u1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
Mouse cursor disappears over the Java Window, though sometimes it seems to flash into view for a fraction of a second, but only while moving it.
Cursor is visible inside the window, but only when the java window does NOT have focus. One can see that by switching back and forth with ALT-F3 and ESC.
The cursor functions normally and spot-on, even though it is invisible.
Same symptoms with the official and with Enders client.
I don't think it's the system, since it works perfectly otherwise, but the setup is like this:
Thinkpad W701
Nvidia Quadro FX 2800M 1GB
Nouveau
Debian 64bit 8.4 Jessie
KDE
Game looks perfect otherwise, but is unplayable with invisible pointer.
