Description
customer reporting a NPE from :
 at com.sun.deploy.net.proxy.WNetscape4ProxyConfig.getNSVersion(Unknown Source)
at com.sun.deploy.net.proxy.WNetscape4ProxyConfig.getBrowserProxyInfo(Unknown Source)
at com.sun.deploy.net.proxy.WDefaultBrowserProxyConfig.getBrowserProxyInfo(Unknown Source)

at com.sun.deploy.net.proxy.DeployProxySelector.reset(Unknown Source)
at com.sun.javaws.Main.initializeExecutionEnvironment(Unknown Source)
at com.sun.javaws.Main.main(Unknown Source)

looks like getNSVersion() relys on windows registry entry:
(HKEY_LOCAL_MACHINE, "Software\\Netscape\\Netscape Navigator")
and will crash if it is not set.

EVALUATION The is caused becuase there is no check in the code to see if a valid Regitry key was actually retrieved. ###@###.### 2005-06-10 12:11:23 GMT
