I'm not sure snappy1.0.3-java even works. The native part isn't compiled (the SnappyNative.h and SnappyNative.c files in src/main/java/org/xerial/snappy). So the libsnappy1 dependency is bogus and could be removed.
I suggest removing snappy1.0.3-java and use snappy-java instead. This one is known to work. picard-tools is the only reverse dependency of libsnappy1.0.3-java, I'll prepare an update. Emmanuel Bourg
