Thanks, Alan!

The extra Names added to KNOWN_NAMES was my doing, and it was based on 
commonly used attributes in Jar file manifests scanned from a set 
commonly used applications as an alternative to building up a Name cache 
dynamically (which is frought with other perils). The chose extras gave 
a marginal but measurable improvement in startup to a wide array of 
applications as a result, and their inclusion is strictly an internal 
implementation detail. If you insist on having them removed I won't 
object, but I believe it's an harmless optimization.
