A DESCRIPTION OF THE PROBLEM :
In certain situations, FileOutputStream.close() re-entrantly (i.e., recursively) invokes itself.

This behavior is horrible as it creates havoc for any sub-classes of FileOutputStream that override close() in order to perform any work at that point in lifecycle of the stream. At the very least, it's undocumented.

I have verified this bug occurs in: JDK 1.8.0_312, JDK 11.0.16, and JDK 18.0.2.
This bug occurs in JDK 8 It does occur in JDK 11, JDK 18.0.2, and presumably all versions in between.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test program below.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
java.lang.Throwable: close() invoked here
at ReentrantClose.close(ReentrantClose.java:12)
at ReentrantClose.main(ReentrantClose.java:19)
ACTUAL -
