Update to 0.0.17-SNAPSHOT version for development purposes. Remove superfluous jar packaging tag, that's the default. Add url tag linking to Kusti's PJC page. Fix some assorted white space issues.
Remove old 3.2.7 JNA jar from lib directory and update POM to reflect current dependency of JNA 3.5.1.
Remove executable permissions from two old jars.
Switch to in-house exception to allow clients to cleanly handle PJC failures. This is a non-breaking change for existing clients as the new exception subclasses the old one and will be caught with old code too. This commit, sadly, includes some trailing white space removal automatically done by my IDE.
