It seems that Sun's implementation does not return ZipInputStream.

ins.getClass().getName()          returns "java.util.zip.ZipFile$2"
ins is subclass of ZipInputStream returns false.

JDK version is:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)

Because I am trying only with compressed jar file yet, I don't know about that.

> What are the number you expect with the example you posted?
The expected return value is a number of bytes of oritinal resource size
(uncompressed size).
