Answer 1

The NoClassDefFoundError description is, from the SO tag:

The Java Error thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found. The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

Or better:

NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time.

from this page. Check it, there are some ways to solve the error. I hope it helps.

Answer 2

If still there's someone out there dealing with this. It looks like you are missing the jcf-release.aar library which should come together inside the jabberGuestSDK package.
