JDK-6267930 - com.sun.deploy.net.proxy.WNetscape4ProxyConfig.getNSVersion can NPE
Description
FULL PRODUCT VERSION :
java version "1.5.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
there is a bug in com/sun/deploy/net/proxy/WNetscape4ProxyConfig.java, inside of the getNSVersion() method.:

==========

private static float getNSVersion() {
  String path = "Software\\Netscape\\Netscape Navigator";
  String s = WinRegistry.getString(WinRegistry.HKEY_LOCAL_MACHINE,
                                                             path,
                                                             "CurrentVersion");
int start = -1, end = -1;

/* Find the beginning and the end of the version number. */
for(int i = 0; (i < s.length()) && (end == -1); i++) {

...

}
============

My machine doesn't have that registry key so your call to WinRegistry.getString assigns 'null' to s.  But then you go ahead and call s.length() in the for loop.

This of course throws a NullPointerException
