We cannot upgrade to JDK 14 due to contractual and security constraints.This is a major problem for us. We just bought 170 Targus docks and we can't use a single one because of this mission critical app crashing.

Can you test your setup with the development builds (18 and 19) of jdk?
This is important as we need to know if the fix that Oracle supplied is sufficient. If so we can push them to port it to older jdk version.
