IsSiteLocalAddress() of inetAddress class returns true for IPv4 Adresses

Question

Any idea why isSiteLocalAddress() method of inetAddress class returns true for IPv4 Adresses?
To my knowledge the IPv4 address can't be a site local address.
Is it expected behaviour?
Here is the snippet of the code.
InetAddress inet=InetAddress.getByName(samplehost);
// Verifying the address type of IPv6.
if(inet.isAnyLocalAddress())
System.out.println("Any local address is " + inet);
if(inet.isLinkLocalAddress())
System.out.println("Link local address is " + inet);
if(inet.isLoopbackAddress() && ip.indexOf(":") != -1)
System.out.println("Loopback address " + inet);
if(inet.isMulticastAddress())
System.out.println("Multicast address " + inet);
if(inet.isSiteLocalAddress())
System.out.println("Site local Address " + inet);
if(ip.indexOf(":") != -1)
System.out.println("Its an IPv6 global address " + inet);
if(ip.indexOf(".") != -1 && ip.indexOf(":") == -1)
System.out.println("Its an IPv4 global address " + inet);

Here is the output and program for your reference.
D:\DIA>java testIPv6 shash10-w2k3
Host name is shash10-w2k3
Inet Address Object is : shash10-w2k3/192.168.126.1
Site local Address shash10-w2k3/192.168.126.1
Its an IPv4 global address shash10-w2k3/192.168.126.1
