This mail was stuck, awaiting moderation as it was sent from a mail 
account that is not subscribed to the list. Thank you for the report. If 
allocating of the Cleaner were to fail with OOME or something else then 
it would leak.  It is tracked by JDK-8294717 [1] and has been fixed in 
the main line for JDK 20.
