Interesting, can I get you to go to a command prompt and do "java -version"?
This is what I have been testing over on Win 8.1:
Code:
java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)
Also 7u40 on Linux Mint 16.
