Hi Igor,

https://bugs.openjdk.java.net/browse/JDK-8146550

Thanks,
Filipp.

I noticed that there is no /test/lib-test isn’t a part of any test-suites, hence moving test to test/lib-test implies extra work in infra. given that I think it’ll be better to do it lately and separately from 8066599. please file an RFE for that.
