Delivered 3rdParty jars are not equal the jars while compilation

The SOSFTP setup contains especially jasperreports-1.2.5.jar but jasperreports-3.6.0.jar is used at complation.
The other 3rdParty jars will be checked too.

Hence the setup requires a script which deletes "old" 3rdParty jars to avoid that several versions of the same jar are in the classpath.
