In later JDKs (11+), JavaNativeFoundations (JNF) framework has has been removed from the JDK sources. See JDK-8257852 with its 8 related bugs which amounts to the total work required to get JNF removed from the JDK 8 source tree.

Removal of JNF would be required to be able to build JDK 8u on a recent MacOSX version. For example, when compiled with an SDK which doesn't have the JNF framework (e.g. X Code 15.x) as part of the SDK.

In order to get the GHA job for macosx re-instated, we'll have to work-around the JNF requirement until a real fix lands (JDK-8257852). This is so that we'll have pre-integration build testing on MacOSX.
