I maintain the mkgmap and splitter packages in the Arch Linux AUR. [1] [2] As far as I can tell, both of these applications require Java 8. For example, if splitter is executed with Java 7, it will throw a java.lang.UnsupportedClassVersionError. [3] Consequently, I've set both mkgmap and splitter to require Java 8. However, the mkgmap dev instructions indicate that Java 7 is supported. Is Java 7 supported?

When responding, please cc me, as I'm not subscribed to mkgmap-dev.
