BuildContext.getValue(String)becomes<T> T getValue(String key)so callers no longer cast;DefaultBuildContextcasts with@SuppressWarnings("unchecked"). The change is binary compatible, since the erased descriptor stays(Ljava/lang/String;)Ljava/lang/Object;, and source compatible: callers assigning toObjectand implementations declaringObject getValue(String)still compile.Closes #42
Verified:
mvn -B -ntp verify→ BUILD SUCCESS;javap -sshows the unchanged descriptor; the module skips test execution, so the new test is a compile-time check that fails to compile on master
