JWT Signature verification failed , java to php

I share with you the first codes

php codes http://ift.tt/2bBWgjl line 22

JwtTester.java http://ift.tt/2blmsRD line 22

Token created in java code I wrote in php server does not match the token. Although I can not verify the same key on both sides

I'm using github.com/jwtk/jjwt in java code and http://ift.tt/1vU0OaY in php codes

same with java code and data in key , consists of different token when I create the token in only PHP
