Hi,

does this work now? This seems to be a problem with Oracle JRE on Windows. The [respective page](http://www.oracle.com/technetwork/java/javase/jre-8-readme-2095710.html) says:

```auto
    jre\bin\server\
        On Microsoft Windows platforms, the JDK includes both
        the Java HotSpot(TM) Server VM and Java HotSpot Client VM.
        However, the Java SE Runtime Environment for Microsoft Windows
        platforms includes only the Java HotSpot Client VM. Those wishing
        to use the Java HotSpot Server VM with the Java SE Runtime
        Environment may copy the JDKs jre\bin\server folder to a 
        bin\server directory in the Java SE Runtime Environment. Software
        vendors may redistribute the Java HotSpot Server VM with their
        redistributions of the Java SE Runtime Environment.

```

I suggest you just install a JDK. Then you should be fine (or you use the workaround they suggest).

Daniel
