Description

Currently, reflection tricks are needed to obtain SPI name (this is now stored in static NAME fields in each factory class) from a concrete factory class. While it is easy to implement that logic, it would be much better to provide unified APIs to get SPI name from a factory class. In other words, the APIs would provide "inverse" operation of lookupClass(String) method.
