tool to compare compatibility of Java library API
Java API Compliance Checker (Java ACC) is a tool for checking backward binary
and source-level compatibility of a Java library API. The tool checks classes
declarations of old and new versions and analyzes changes that may break
compatibility: removed methods, removed class fields, added abstract methods,
etc. Binary incompatibility may result in crashing or incorrect behavior of
existing clients built with an old version of a library when they are running
with a new one. Source incompatibility may result in recompilation errors with
a new library version. The tool is intended for library developers and
operating system maintainers who are interested in ensuring backward
compatibility, i.e. allow old clients to run or to be recompiled with newer
library versions.
