Could it be Java 1.7 <-> 1.8 problem?

szepeviktor commented 8 years ago

Maybe?

Since version 0.2, Java 8 is required.

szepeviktor commented 8 years ago

Yes, on Java 8 there's no problem. https://travis-ci.org/szepeviktor/ip-info/builds/126926046

I think it would be better if this was compatible with Java 7. In particular because this is what is available on Travis.

With the recent updates, I need sudo: required and I need to apt-update and install Java 8, which makes builds run much slower. Are Java 8 features absolutely required?
