Unknown initial character set index ’192′ received from server

Detail exception is :
java.sql.SQLException: Unknown initial character set index '192' received from server.
Initial client character set can be forced via the 'characterEncoding' property.


Solution :
find my.ini file of mysql 
And comment two lines bellow :

#collation_server=utf8_unicode_ci
#character_set_server=utf8


So far it works for me . 
But this is a known bug and fixed earlier hear .
