fix: ensure that the java.class.path property returns the correct classpath

[0utplay]

Motivation

Due to the fact that we use the wrapper to start the application the jvm misses to add the platform jar to the classpath. But we also can't add the platform to the classpath before the wrapper is not started as this would cause us to start the platform directly.

Modification

After the wrapper is started we append the platform jar to the class path property. Therefore the jar is not loaded directly but is still part of the class path property and platforms can depend on the property.

Result

Platforms can depend on the default java behaviour which is to add the own platform to the cp.
