With the latest kestrel promotion (I) SwingSet as an applet no longer works.
The exception that is generated is:
java.security.AccessControlException: access denied
(java.util.PropertyPermission http.keepAlive read)

Looking at the code for HttpClient you can see that getHttpKeepAliveSet doesn't use a doPriviledged, resulting in the applet security manager being used, which doesn't allow access to 'http.keepAlive' and thus this exception is generated.

Below is the trace from the SwingSet not loading bug with Hotspot removed.

Here's the trace w/out hotspot (just classic):

JAR cache enabled.
