com.izforge.izpack.util.LibraryRemover

public class LibraryRemover
extends Object

This class tries to remove a given list of files which are locked by this process. For this the paths of the files are stored in a temporary file and a new process will be created. The class files which are needed by the new process will be unpacked from the jar file under users temp dir in a "sandbox". The new process receive the path of the temporary file and some other information. After a wait intervall it reads the path file and removes all files which there are listed. Next the created "sandbox" and the path file will be removed. This class uses the characteristik of the system loader that jar files will be keeped open, simple class files will be closed after loading a class. Therefore jar files are locked and cannot be deleted, class files are not locked and deletable.
The idea for this stuff is copied from Chadwick McHenry's SelfModifier in the uninstaller stuff of IzPack.
