Ridiculous. Go's lack of verbose classes and lack of inheritance, pass everything by value, the existence of pointers, first class concurrency primitives, compile to binary / no interpretation/JIT, lack of a VM, built in unit testing/benching, fast compile times, memory usage, easy C integration, etc etc all make it very different from Java.
I've been writing Go full-time for over 2 years and used to write mostly Java/C#, so I should know. When I started with Go and ported many of my personal Java applications, they all were much more maintainable and straight forward in Go.
Of course C had always been favorite language, and all I ever really wanted was a "modern" C, so I am probably biased.
