JI-9041860 has now been transferred to the JDK project as:

Our support engineer was not able to reproduce the problem, so closed it 
as such. Based on the additional information you provided, I have 
reopened the bug and will ask someone on our team with a physical Linux 
setup to try to reproduce it.

To answer your question, we are not aware of any such leaks.
