> We need a new class loader that does not leave open file locks when
> destroyed. The URLClassLoader will only close the jar files and subsequently
> release the file locks, when it is garbage collected. It is common for
> programming mistake to leak references to classes (even the JVM has several
> leaks), and these leaked classes have hard references to the class loader
> which prevent the class loader from being garbage collected. On Windows the
> jar files referred to by a URLClassLoader can not be modified or deleted
> until the class loader is garbage collected which in too many cases means JVM
> exits. This prevents redeployment from working since, the directory can not
> be deleted.
