    Description

      When I by luck I had left value in properties file with trailing space it thrown such error.
      example :
      group.id=MyGroupID<Blank Space>

      when I read this group.id from properties file and put it to ConsumerConfig, the error appeared as below stacktrace.

      Exception in thread "Thread-1003" kafka.common.InvalidConfigException: client.id MyUserDataReaderGroup is illegal, contains a character other than ASCII alphanumerics, '.', '_' and '-'
