Does fabric8-karaf-1.1.0.CR2 run?

[tdudgeon]

I'm trying fabric8 for the first time, so may be doing everything wrong.
But I download the karaf version from here: http://fabric8.io/gitbook/getStarted.html
Unzipped and ran and get a whole lot of stack traces like this:

Please wait while Fabric8 is loading...

The web console is not running after that.
Tried this on Mac and Windoze with same result.
Is something badly broken with the distro?

Are you using Java8 by any chance? If so currently we only support java7.

But support for java8 comes when we upgrade to Karaf 2.40 when its released.

[tdudgeon]

No, I've tried on Java6 and Java7 with the same result.

[tdudgeon]

Sorry, correction, I was running on Java6. I switched to Java7 and it runs OK.

[davsclaus]

Ah good to know, you can search the web about

Unsupported major.minor version 51.0

And find information that this message means that java 7 is required.

Also if there was still some issue, checking what JAVA_HOME is set to, or check the bin scripts that is used to start fabric may help indicate if a different java was picked up, than you would have thought.
