@katyapav Is the failure observed on vector-unstable branch of panama-vector?
The code in this pull request is from vector-unstable branch.
The bug report https://bugs.openjdk.java.net/browse/JDK-8233199 refers to repo-valhalla and not
panama-vector:vector-unstable. @PaulSandoz is doing final testing of the pull request today before integration tomorrow
hopefully.
