Stray junit imports in KAPProcessor prevents building unless test target is invoked.

Also, java version defaults to 1.5 in the mvn that comes on yosemite so I had to add a plugin reference for the build section to specify java 1.7.

Pull request forthcoming.

Somehow the image is corrupted as its converted from the KAP format to PNG format. This only happens for some files. Needs some-one who understands image format reading/converting

This bug sounds similar, https://bugzilla.redhat.com/show_bug.cgi?id=662230
Relevant code is in maptools project line 641 getImage() method.

Am struggling with this. Builds OK but doesn't create the tile pngs either at all or properly. Am trying to convert 6161.kap within the Stockholm archipelago. Directory structure and top level files get created but the tile pngs never get created because they are considered 'out of bounds' by the create image function in the KAPP processor..

Even the default NZ kaps included with the distribution don't get created ok. The pngs seem to get created but they are blank. No errors in the build log.
Any ideas? What am I doing wrong?
