Hi again,

I asked this question in the relevant RFR threads, but they apparently went unnoticed. Therefore, 
let me ask this in a new thread.

This is about the following issues:
   8249192: MonitorInfo stores raw oops across safepoints
   8251118: BiasedLocking::preserve_marks should not have a HandleMar

At the time 15.0.1 was open for pushes, it had been stated that both issues were pushed to some CPU 
repo. I was under impression it was to appear in 15.0.1 release, but it did not. So, there are no 
changes in current 15u:
   https://hg.openjdk.java.net/jdk-updates/jdk15u/log?rev=8249192
   https://hg.openjdk.java.net/jdk-updates/jdk15u/log?rev=8251118

There is still the "Resolved" backport in 15.0.2 for one of the issues:
    https://bugs.openjdk.java.net/browse/JDK-8251485

...and there is no resolved backport for another.

So, is there a private 15.0.2 CPU repo within Oracle? Are we expecting both issues to come with 
15.0.2 CPU push? Even in this case, can we push the change to open 15.0.2, so we would be able to 
test it in open repositories before next CPU hits?
