Hi,

doesn't 1.5.0 introduce breaking change since from implementation perspective changing method access from protected to public is not compatible (one who implemented it as protected can't do this anymore)?

see https://github.com/prometheus/client_java/pull/1800/changes#diff-e2e698a852fe81e25539a14fb61eb5d7f987750b704bcbc7df7f474e8821e1baL30
