Hi Elias,

Thank you for your contribution. This actually makes a lot of sense.

I've merged the change and released it in v0.4.0.

i'm happy that somebody else has a use case for this library and would love to hear more about your usecase of hyperscan-java, if you don't mind to share.

Thanks a lot

• M.

@gliwka Mostly using it to match HTTP traffic.

BTW, any chance of adding <scope>test</scope> to the JUnit dependency and pinning it to a version that is not RELEASE? Maven 3 no longer recognizes that tag.

Fixed in #11 (v0.4.1)

Thanks for the hint - java is not really my "native" langauge 😃
