Fix file handle leak in JarFileTests 

The JarFile was not being closed which linked a file handle and caused
a test failure on Windows.

The local variable has been renamed as, when declared in a
try-with-resources, Checkstyle was confused by the shadowing of the
jarFile field and required references to jarFile within the try-block
the be prefixed with this.
