Provides an abstraction for use by the various classes that need to scan
JARs. The classes provided by the JRE for accessing JARs (JarFile and
JarInputStream) have significantly different performance
characteristics depending on the form of the URL used to access the JAR.
For file based JAR URLs, JarFile is faster but for non-file
based URLs, JarFile creates a copy of the JAR in the
temporary directory so JarInputStream is faster.
