Apache Sling - OSGI framework exception when starting in Windows

Question

I received the following error message when starting Sling on Windows with Java 1.7 (see below). I'm using Sling 6 (http://www.apache.org/dyn/closer.cgi/sling/org.apache.sling.launchpad-6-standalone.jar). Any idea what could be wrong?

Last time I tried using the same Sling version on Mac OSX and it worked perfectly.

Answer 1

I had exactly the same error when using java 1.7. After switching to 1.6 everything seems to be fine. You check your java version by typing java -version in the terminal.
