Encoding negative numbers makes the program stall

[jw2476]

Using varint.encode(-1) makes the program indefinitely stall.
Is this expected behaviour, because I really need to be able to write negative varints.

I faced the same problem. According to the wikipedia article about Variable-length quanitity only unsigned integers are defined in the basic implementation. So you need another variant of varint like ZigZag encoding.
