*
*
*
* To comply with this interface, an implementation must be thread safe and
* address both the possibility that only a single instance is created and used
* throughout and that new instances are created as desired.

*
* This information, in turn, enables the implementation to use the same mechanism
* to set dependencies as needed.
*
* If this information is not given, an implementation
* should avoid using SPIs and instead use
* declarative services
* for dependency injection as specified by OSGi. Note that this also applies to
* several newInstance() methods in the Java API.
*
* The class that created an instance with SPI must call this method before
* putting it to use.
