If so,just like jdk lower version can't run higher version class,maybe you can package your application jar file use jdk 1.6 and test it again. > Creating Kafka Producer on application running on Java 1.6 > -- > > Key: KAFKA-4823 > URL: https://issues.apache.org/jira/browse/KAFKA-4823 > Project: Kafka > Issue Type: Bug > Components: KafkaConnect >Affects Versions: 0.10.1.1 > Environment: Application running on Java 1.6 >Reporter: Aneesh > > I have an application running on Java 1.6 which cannot be upgraded.This > application need to have interfaces to post (producer )messages to Kafka > server remote box.Also receive messages as consumer .The code runs fine from > my local env which is on java 1.7.But the same producer and consumer fails > when executed within the application with the error > Caused by: java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major > version; class=org/apache/kafka/clients/producer/KafkaProducer, offset=6 > Is there someway I can still do it ? -- This message was sent by Atlassian JIRA (v6.3.15#6346)
