Compile errors when building arquillian with Luna target platform

When building the arquillian component with Luna TP(tpc.version=4.40.0.Alpha1-SNAPSHOT) there are the following compile errors:

[ERROR] import org.eclipse.osgi.framework.adaptor.BundleClassLoader;
[ERROR] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[ERROR] The import org.eclipse.osgi.framework.adaptor cannot be resolved
[ERROR] 
...
[ERROR] || tmp instanceof BundleClassLoader)
[ERROR] ^^^^^^^^^^^^^^^^^
[ERROR] BundleClassLoader cannot be resolved to a type

The errors are caused by the change of OSGi internals.
The org.eclipse.osgi.framework.adaptor package and the BundleClassloader class have been removed from Luna.

The changes aren't compatible with the previous Eclipse versions, so we need a separate branch for Luna.
