[Bug libgcj/13972] New: gcj's URL() does not handle ContextURL + "/redir?http://domain2.com/index.html" correctly.

Hi,

I noticed that the URL function in libgcj's java.net.URL does not properly
process requests like:
  URL("http://domain.com";, "/redir?http://domain2.com/index.html";);

This is because at the start of the function, context is set to null if spec
contains a :// anywhere, but even in the comment at the top of that function it
is mentioned that:
    /* A protocol is defined by the doc as the substring before a ':'
     * as long as the ':' occurs before any '/'.
 
Hence I submit the following diff against CVS:

--- URL.java    31 Dec 2003 10:55:40 -0000      1.34
+++ URL.java    2 Feb 2004 01:18:04 -0000
