Review comment:
Good question.
I have not found any other ways to do it using some Java API.
The message is documented though, e.g. in Oracle Java
[8](https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/memleaks002.html)
and
[11](https://docs.oracle.com/en/java/javase/11/troubleshoot/troubleshoot-memory-leaks.html#GUID-19F6D28E-75A1-4480-9879-D0932B2F305B).
