A DESCRIPTION OF THE REQUEST :
The -C option to change the directory is not supported when extracting files from a JAR file.

e.g.:
 jar xf test.jar -C c:\temp *

JUSTIFICATION :
It would make scripts clearer, that have to unpack and repack JAR/WAR files.

The x (extract) command would work analogous to the c (create) command.

I assume that Implementing the -C option for the extract command would be easy.
