OpenJDK 16 (ee1d592a9f53+ tip) - compilation error in "sharedRuntime.cpp:2849"

[daniel.daugherty at oracle.com]

That looks like this bug:

     JDK-8253375 OSX build fails with Xcode 12.0 (12A7209)
     https://bugs.openjdk.java.net/browse/JDK-8253375

which is fixed in JDK16-b16 (integrated on 2020.09.22).
