This PR fixes a false negative in range analysis: when
v1 == v2and some bound applies tov2, then the same bound is considered forv1. If the bound precedes the equality, then it was already considered. However, if the bound succeeds the equality, then it was missing previously.Differences job: https://jenkins.internal.semmle.com/job/Changes/job/Java-Differences/918/
