System.runFinalizationOnExit has been deprecated since 1998 (JDK 1.2) and this method is inherently unsafe. I am thinking to propose this method in JDK 9 to throw UnsupportedOperationException.
I believe it's rare for existing applications using System.runFinalizationOnExit. My analysis on Maven Central ~315K artifacts that show about ~15 unique artifacts calling System.runFinalizationOnExit while they all come from only 5 classes. Any thought/feedback? Mandy
