Running ant with jdk7

[Kelly O'Hair]

Has anyone been running ant with jdk7 or openjdk7? Just curious if anyone else
has run into this problem. My ant script does something like:

  <unzip src="${drop.bundle}" dest="${drop.dir}"/>

But when I have ant run with jdk7 (jdk7/bin in my PATH), I'm getting
this exception:
