re GNATS libgcj/38 (Static initializer in DecimalFormat eventually depends on itself)

Browse Source 
2000-02-25  Bryce McKinlay  <bryce@albatross.co.nz>

        * java/net/URLConnection.java (initializeDateFormats): New
        private method.
        (getHeaderFieldDate): Call initializeDateFormats if required.
        locale, dateFormat1, dateFormat2, dateFormat3: Don't initialize
        these.
        Fix for PR libgcj/38.
