Request for Review: 6693244

[Christopher Hegarty -Sun Microsystems Ireland]

Hi Michael,

This is a forward port to JDK7. The very same fix is already in 6u10, 
5.0uXX and 1.4.2_XX.

There is the possibility that endAuthRequest can be invoked twice with 
the same key. endAuthRequest in turn invokes requestCompleted, which 
contains the assertion. If an authentication request succeeds it will be 
added to the cache, Authentication.addToCache, this method will invoke 
endAuthRequest. HttpURLConenction.getInputStream has a finally block 
that will also invoke endAuthRequest.

6693244: Java Web Start app fails on 6u10 beta w/ AssertionError in 
AuthenticationInfo.requestCompleted
