We will need to update this, something similar to... diff --git a/src/java.base/share/classes/java/net/doc-files/net-properties.html b/src/java.base/share/classes/java/net/doc-files/net-properties.html --- a/src/java.base/share/classes/java/net/doc-files/net-properties.html +++ b/src/java.base/share/classes/java/net/doc-files/net-properties.html @@ -58,7 +58,8 @@ applications that depend on the representation of an IPv4 address (e.g. 192.168.1.1).
