RFR: 8294378: URLPermission constructor exception when using tr locale

[Ryan Wallace]

Hi all,

Please review this fix for  Invalid characters in hostname exception. 
This was due to the URLPermission.parseURI() method calling String.toLowerCase() and returning a non ASCII characters in the case of the tr Locale.  The fix was to use the HostPortrange.toLowerCase() method further down the stack which is Locale safe.

Thanks,
Ryan.
