Hi Chris,

Yes, they are going directly to jdk9/dev, I forgot to add the group, adding now.

No, this is mostly not redundant, as the jdk/testlibrary comntains many files specific for jdk only. Only a relatively small number of files are duplicated between hotspot and jdk.

No, we are not proposing a new repo. The changes are in the 'top' repo.

>test/lib/testlibrary/jdk/testlibrary/RandomFactory.java was updated

We are going to upmerge the changes then

>Is there any special update needed to jtreg to support this?
For thse changes no jtreg update is required.
However, there are plans for the jtreg to prohibit referencing any @libraries above the repo root unless such libraries are directly specified in TEST.properties
If jtreg thus prohibits  our using /../../test/lib (because it's above the root) we will have to additionally make a change to jdk and hotspot TEST.properties
