question: public Map < String , String > environment ( ) { String base64 = toStringBase64 ( ) ; if ( base64 == null || base64 . length ( ) == 0 ) { return Collections . emptyMap ( ) ; } Map < String , String > environment = Maps . newHashMap ( ) ; environment . put ( BaggageUtils . BAGGAGE_ENVIRONMENT_VARIABLE , base64 ) ; return environment ; }
target:  Encodes the baggage to strings to set as environment variables, which will then be picked up in a child process
