Some weeks ago I wrote you about tests in a Java package of Debian-med,
that were failing on some computers and passing on others.
I have just found this was due to a file not being closed with the
close() method. Afterwards some other tests were counting open files and
failing because of this file not being closed whereas they expected it.
I guess the Java garbage collector was closing the file early enough on
some computers, and not on others.
Maybe this case will help in the future when meeting other such situations.
