/**
 * Creates a Loader that processes bootstrap system composite, which uses a constrained version of the SCA programming model. The constraints are:
 *  * 
 * The only implementation type allowed is system
 * The only service contract type is a Java interface found through introspection
 * Resolution of SCDL artifacts by QName is not supported; scdlResource must be used
