/**
* An archive driver which builds JAR files.
* JAR files use {@value #DEFAULT_CHARSET} as the character set for
* entry names and comments.
*
* Other than this, JAR files are treated like regular ZIP files.
* In particular, this class does not check a JAR file for the
* existance of the META-INF/MANIFEST.MF entry or any other entry.
*
* Instances of this class are immutable.
