InetAddresses.forString throws IllegalArgumentException on valid IPv6 address

[GoogleCodeExporter]

What steps will reproduce the problem?
1. InetAddresses.forString("::7:6:5:4:3:2:1")

What is the expected output? What do you see instead?
I expect a java.net.Inet6Address object.
Instead I get exception: "java.lang.IllegalArgumentException: '::7:6:5:4:3:2:1' 
is not an IP string literal."

What version of the product are you using? On what operating system?
guava-r07 // Compiled from InetAddresses.java (version 1.5 : 49.0, super bit)
Windows XP Professional 32bit

Please provide any additional information below.
Cases: "8:7:6:5:4:3:2:1", "0:7:6:5:4:3:2:1", ":7:6:5:4:3:2:1" "::6:5:4:3:2:1" 
works all right, it happens when only the first group are zeros (suppressed to 
double colons).
