Looks like they dropped support for openjdk7

"Expected feature release number in range of 9 to 15, but got: 7"

Will need to probably switch to a higher version one, thanks

I remember this, it's just a matter of changing openjdk7 to openjdk9 or oraclejdk7 (or 8), if you define Java version 7 in your POM files.

Regarding #75; I've made a Trie implementation @ org.comroid:trie and I'm currently investigating whether its possible to use a Trie structure to support extreme String sizes. I'm using the 'develop' branch from before for this.
