Launcher for 1.6 pre-release does not allow offline play when behind a proxy.

When attempting to start Minecraft while the computer is connected to a network with a proxy (firewall) the launcher does enable the "Play Offline" button.

The launcher for 1.5.2 recognized eventually that it could not make a connection and offered offline play with in about a minute. This new launcher does not.

As a workaround I attempted to start the application with a batch file and configured JVM parameters -Dhttps.host=**.*.*.** -Dhttps.port=8080 -Dhttp.host=**.*.*.** -Dhttp.port=8080 -jar Minecraft.exe. This however only allows the MOJANG information to appear in the launcher but still no offline play.

The only way I can start the game is if I first disconnect my computer from the network. Then the launcher pretty quickly realizes that there is no network connection and enables the "Play Offline" button. Then I can connect my computer back to the network.

Nothing really serious, I just like to play around during my lunch time.

The following is the output of the launcher:

I have found a workaround for this issue. You must create a new profile with your Mojang credentials, then login to the profile outside the proxy. Then edit the profile and change the JVM arguments to the -Dhttp.proxyHost=**.*.*.** -Dhttp.proxyPort=**** -Dhttps.proxyHost=**.*.*.** -Dhttps.proxyPort=****. Once this is done then the Play Offline button became available.

Maybe it can be done while behind the proxy I'm not sure, but at least this is one possible workaround, hopefully it helps others until this problem is worked out.
