Investigating further it looks like this bug only affects Turtle inputs so
one workaround is simply to use formats other than Turtle for input.

This is a bug in Elephas which I've filed as JENA-1075 [1]

Fix looks to be fairly trivial, once the fix is committed (probably in an
hour or so) you can try using the development SNAPSHOT builds which should
resolve the problem.  To do this change the version to 3.0.1-SNAPSHOT in
your <dependency> declarations in your POM
