On MS Windows 10 OS 64-bit build of JDK 12 from the repository "http://hg.openjdk.java.net/jdk/client" fails.

In the local build environment it was practically proven that reversion of 2 fixes: JDK-8212083, JDK-8211432 allows to resolve the build failure, therefore the reason of the build failure is the fix for the bug JDK-8211432.
