I can get rid of this error, if i replace the
xstream-1.2.2.jar
by a newer version (changing the name of e.g. xstream-1.4.1.jar to 
xstream-1.2.2.jar)
...but that then gives another error with Run as (in SIM) of a script:

digging into that issue it seem to be a problem of the used xstream/jre7
http://stackoverflow.com/questions/9621372/xstream-no-args-constructor-error

and confirmed, that the SIM editor opens when running Eclispe under that jre:
eclipse.buildId=4.3.0.M20130911-1000

workaround:
use java 1.6, modify eclipse.ini (add

This problem should be fixed because the latest Eclipse IDE doesn't run with 
Java VM 1.6 any more - and it is not the easiest thing to find an old Eclipse 
IDE which runs with Java 1.6.
Latest Eclipse build needs at least Java 1.7

This issue should be moved to critical.

Java 1.6 support and security updates have ended ages ago, and keeping Java 6 
on your system is, by now, an absolute hazard.
Even Java 1.7/7 will only get security updates and official support til April 
2015.

LSLForge needs to work with Java 8.
