NullPointerException in MessageFactory when trying to test on real device

[Gyran]

I have built the latest snapshot of the dev branch and the mac I run on has xcode 6.4. I start the standalone server with the -beta flag. When I check the hub status page everything seems fine and I can see my plugged in devices. When I try to connect to the driver with these capabilities:

{
     "CFBundleName": "Safari",
      "device": "iphone",
      "language": "en",
      "locale": "en_GB",
      "simulator": false
}

Safari starts but the crash after a few seconds. I have tested both with an iphone running 8.3 and 7.0.4.

Am I missing something or have I forgot something?

I'm getting the same error- testing on 7.1.2 and 8.3.

Seems like I'm getting a report setting message with a missing WIRSIMULATORPRODUCTVERSIONKEY field. It then tries to find the version with every successive message too, and still doesn't have success.

Raw Message:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>__selector</key>
<string>_rpc_reportSetup:</string>
<key>__argument</key>
<dict>
</dict>
</dict>
</plist>

Additionally, using /wd/hub/capabilities/all I can tell the versions of the devices- that part is detected just fine from there.

I've added a fix for this- the physical device does not put the same information into all of its messages, hence the NPE. The version list was also incomplete.
