network manager gets exceptions opening https connections

[ddyer0]

Preparing to convert my HTTP to HTTPS, I find that my lower level use of the network manager fails when opening HTTPS connections. This works fine with http requests, and curiously, also works fine with https on real devices. This is a simulator only problem.

run the attached program (there's nothing special about the URL) and on the simulator the network thread gets a SSLHandshakeException and fails to call either of the callbacks. On real devices, the normal contination callback is used.

package dtest.boardspace;
//
// this version shows the network code getting an exception 
// opening a https connection.

Looking a little further into this, I think the immediate problem is that the certificate for boardspace.net is not sufficiently trusted by the JVM, so the correct response would be to call the error callback.
