Hi, I got the following error after updating my Cassandra system from Java 1.8.0_112 to 1.8.0_162:
java.lang.AbstractMethodError: org.apache.cassandra.utils.JMXServerUtils$Exporter.exportObject(Ljava/rmi/Remote;ILjava/rmi/server/RMIClientSocketFactory;Ljava/rmi/server/RMIServerSocketFactory;Lsun/misc/ObjectInputFilter;)Ljava/rmi/Remote; I did the usual Googling and here’s what I’ve concluded: * Between Java 1.8.0_152 and 1.8.0_162, the interface com.sun.jmx.remote.internal.RMIExporter was changed to add a 5th argument to the exportObject method. The class in a Sun “internal” package so it probably wasn’t intended for use outside of the JDK. * Cassandra references RMIExporter in org.apache.cassandra.utils.JMXServerUtils but uses only 4 arguments in the exportObject method: https://github.com/apache/cassandra/blob/cassandra-3.11/src/java/org/apache/cassandra/utils/JMXServerUtils.java * I was running on Cassandra 3.11 but I also tried 3.11.1 and the problem remained. I couldn’t find anyone else reporting this bug so I must be doing something different. Have others seen this bug? Or is it something obvious, i.e. does Cassandra not support running on Java 1.8.0_162 yet? Thanks! Stephen
