Abstract
The finalize() method should only be called by the JVM
after the object has been garbage collected.
Description
While the Java Language Specification allows an object's
finalize() method to be called from outside the finalizer,
doing so is usually a bad idea. For example, calling
finalize() explicitly means that finalize() will be called
more than once: the first time will be the explicit call and
the last time will be the call that is made after the object
is garbage collected.
Examples
The following code fragment calls finalize() explicitly:
// time to clean up
widget.finalize();
