Ondrej Dockal commented on JBIDE-26598:
---------------------------------------

Except mentioned above corner case, I would like to mention that there is an error while connecting to local openJDK 11 process from openJDK 8 runtime.

Nevertheless, I would create another jira for this two cases, as tooling works despite those errors.
