Plugin fails to load on Spigot 1.8.7 #1

Closed bjmc closed 8 years ago

I'm getting this error when starting Spigot with the JuicyRaspberryPie plugin. This is on Ubuntu 15.04 using Java 7 (openjdk-7-jre). Please let me know if any other details would help for debugging.

Same error on Ubuntu 14.04. Tested with both java sdk 6 and 7. Any idia?

Please use JDK 8( or jre 8) from oracle. I tried just now and it works on both windows and Ubuntu 14.04, with spigot 1.8.8.

The plugin use a java8 feature (thought in retrospect, it's not necessary) so it only works with Java 8, sorry.
