Java WebStart error - Nullpointer at JREInfo.validateHomeJRE_int(Unknown Source)

Hello

I'm a newbie at java webstart and have problems starting the webstart viewer (javaws -viewer). When I google for the problem I get a lot of links referring to running 32bit JRE on 64 bit windows but I cant see how this is possible in my situation.

Error message when running javaws -viewer:

java.lang.NullPointerException

OS: win7, 64bit

java -version

java version "1.8.0_25"

Java(TM) SE Runtime Environment (build 1.8.0_25-b18)

Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

Starting javaws with -verbose gives the following information before the error occurs:

I'm happy for any suggestion pointing me to the right direction.
