/**
* Creates injector instances, depending on the injection characteristics of the component class.
* It will attempt to create a component adapter with - in order of priority:
*
* - Annotated field injection: if annotation {@link org.picocontainer.annotations.Inject} is found for field
* - Annotated method injection: if annotation {@link org.picocontainer.annotations.Inject} is found for method
* - Setter injection: if {@link Characteristics.SDI} is found
* - Method injection: if {@link Characteristics.METHOD_INJECTION} if found
* - Constructor injection (the default, must find {@link Characteristics.CDI})
