RFR - 8087190: Regression in sun.net.util.IPAddressUtil.isIPv4LiteralAddress(String)

[Rob McKenna]

Hi folks, looking for a review for this simple change.

The change for https://bugs.openjdk.java.net/browse/JDK-8040747 
initialised each octet to 0. This meant that ... was translated to 
0.0.0.0 before checking the validity of the address.

This small change remedies that.

I just noticed that I neglected to add 8087190 to the @bug tag of 
textToNumericFormat.java. I'll do that pre-push.
