Hi @levant916, thank you for using Lingua and for opening this issue.

I can confirm that this is a bug. This is because the LanguageDetector uses the Java method java.util.Map.merge() internally which is only supported by Java >= 1.8. I will replace it by an appropriate Kotlin method. After this change, the library should run on Java 1.6 and 1.7 as it was originally intended.

Only the FilesWriter classes will need Java 1.8 at least because I make use of the NIO api. But if you don't want to create your own language models, you should be fine with Java < 1.8.

@pemistahl
What if it has to be Java 8? I'm trying to integrate it inside a project that is already using Java 8

@roi3363 There won't be any problems with Java >= 8. This issue was opened because of problems with Java < 8. The library is supposed to work with Java >= 6.
