ADDITIONAL SYSTEM INFORMATION :
Windows / Window 10/ JDK 16 and JDK 17ea

A DESCRIPTION OF THE PROBLEM :
Desktop.browse native peer implementation attempts to CoInitializeEx as COINIT_APARTMENTTHREADED and will fail if there has been a prior call (eg. via JNI) to CoInitialize as COINIT_MULTITHREADED. This problem is new in JDK 16/17ea - see awt_Desktop.cpp:88 in JDK source for point of failure.

REGRESSION : Last worked in version 15

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a native /JNI call that calls CoInitializeEx(NULL, COINIT_MULTITHREADED) and call the native prior to calling Dekstop.getDesktop().browse(url).

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
URL will open in system assigned browser (JDK 15 and earlier)
ACTUAL -
Exception in thread "main" java.io.IOException: Failed to open https://www.google.com. Error message: CoInitializeEx() failed.
