Unsupported major.minor version 52.0

[osigida]

the library is compiled with java 8 which makes it not really usable so far.
better to maintain some backward compatibility, and use at least java 7

exception looks like:
java.lang.UnsupportedClassVersionError: com/wikia/dropwizard/logstash/appender/LogstashSocketAppenderFactory : Unsupported major.minor version 52.0

Any interest in compiling with java 7?

[esiqveland]

Yes, please compile with at most java 7 =)

Unless your code or dependencies absolutely require Java 1.8 you should always set lower version as target. Think about your users. Not all projects are using 1.8 today. You simply make your library unusable for many projects out there.

I checked briefly - looks like the only 1.8 thing in this code is using of Map.getOrDefault() method, which is, obviously, easy to work around.
