public static void normalize(File jar) throws IOException
As stated in Pack200.Packer's javadocs applying a Pack200 compression to a JAR archive will in general make its sigantures invalid. In order to prepare a JAR for signing it should be "normalized" by packing and unpacking it. This is what this method does.
Note this methods implicitly sets the segment length to -1.
jar
- the JAR archive to normalize
