RFR [9] 8175261: Per-protocol setting for not working for JAR URLConnection defaultUseCaches

[Chris Hegarty]

The fix for 8163449 [1] "Allow per protocol setting for URLConnection
defaultUseCaches", does not work for JAR URLs ( which embed URLs to
the actual artifact ).

The problem is that sun.net.www.protocol.jar.JarURLConnection passes
all of the [g|s]et[Default]UseCaches() method calls to the embedded
jar file URLConnection. This means any attempt to control caching for
just JAR URLs fails. "jar" always ends up being treated like whatever
the embedded URL is, which is exactly the case that 8163449 was trying
to address.

JarURLConnection should set the initial cache value of its emdedded
URLConnection ( to the actual resource ), to whatever its initial
value is. Subsequent set/getUseCaches will then behave as expected.
