      Key of the global resource lock that all direct children of the engine descriptor acquire in read mode by default: "org.junit.platform.engine.support.hierarchical.ExclusiveResource.GLOBAL_KEY"

      If any node requires an exclusive resource with the same key in read-write mode, the lock will be coarsened to be acquired by the node's ancestor that is a direct child of the engine descriptor and all of the ancestor's descendants will be forced to run in the same thread.
