unhappy jar binary

[S.P.Zeidler]

Hi,

compiling bsd-port with openjdk7 results in a jar binary that does eg:
% /usr/local/bsd-port/build/bsd-amd64/j2sdk-image/bin/jar xf rt-closed.jar @foo
java.lang.NullPointerException
        at java.lang.String.startsWith(String.java:1433)
		at java.lang.String.startsWith(String.java:1462)
		at sun.tools.jar.Main.extractFile(Main.java:879)
		at sun.tools.jar.Main.extract(Main.java:860)
		at sun.tools.jar.Main.run(Main.java:245)
		at sun.tools.jar.Main.main(Main.java:1133)

This is due to the new extract method not setting cwd, which makes
the bsd-port extractFile patently unhappy. If one adds:

all is well (tm).
