ServiceMix 4.3.0 won't start as downloaded

[Tito]

Hi, I just downloaded ServiceMix 4.3.0 for Windows, unpacked into a dir, and
executed servicemix.bat. The result:

D:\Programs\apache-servicemix-4.3.0\bin>servicemix.bat
Could not create framework: java.lang.ArrayIndexOutOfBoundsException: -1

Shouldn't it run as downloaded?

Thanks,
