Issue	Fix Version	Assignee	Priority	Status	Resolution	Resolved In Build
JDK-8349922	17.0.15	Christoph Langer	P2	Resolved	Fixed	b03

~~JDK-8185862~~ changed the detection of headless mode on Windows by enumerating displays and turning on headless mode when only virtual devices exist. This causes problems with several use cases, mostly for automatic testing, e.g. JDK-8336862, ~~JDK-8340992~~, JDK-8341294.

While the new detection mode seems correct from its idea, we should revert the change for the current LTS update releases and try to focus on fixing issues with explicitly using -Djava.awt.headless=true in the head release.
