The URL constructor throws a java.lang.StringIndexOutOfBoundsException given the
following URL:
  http://www.javasoft.com/jdc/community/chat/index.html#javalive?frontpage-jdc

It can be tested with the following code:

public class Test
{
  public static void
  main(String[] args) throws Exception
  {
    System.out.println(new java.net.URL(args[0]).toString());
  }
}

The problem is in URLStreamHandler.parseURL(). If the URL contains
a fragment then parseURL() is given a limit that excludes the
fragment (from parsing). If in addition, there is a query inside the
fragment then the following piece of code erroneously tries to
remove the query even though it is past the limit. The 
spec.subString() call is given a beginIndex parameter that comes
after the endIndex.

// FIX: should not assume query if opaque
        // Strip off the query part
        if (start < limit) {
            int queryStart = spec.indexOf('?');
            queryOnly = queryStart == start;
            if (queryStart != -1) {
                query = spec.substring(queryStart+1, limit);
                if (limit > queryStart)
                    limit = queryStart;
                spec = spec.substring(0, queryStart);
            }
        }

Incidentally, the problem is with generic URL parsing and is not OS dependent.
