Flow requires applications to be run with java 1.7+. This is because we're using a kafka library that requires 1.7+.
We used to support 1.6+ using when we used an older version of that library but we had to get a newer version to fix important bugs.
We could support 1.6+ if we used the REST proxy for Kafka instead. This is quite a change so I don't expect it to happen in the near future.
In the meantime, the best option is for you to run your app with java 7, if possible...
I guess Kafka required JDK 6+ but my application required JDK 6. Caused by: java.lang.UnsupportedClassVersionError: com/flow/shaded/org/apache/kafka/common/serialization/StringSerializer : unsupported classversion 51.0
Is there any way to resolve this issue?
