Description

Installed new kafka 2.7.0 with scala 2.13, configured and start broker. Checked the process information and found:

/opt/jdk11/bin/java -Xmx1G -Xms1G -server -XX:+UseG1GC -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35 -XX:+ExplicitGCInvokesConcurrent -XX:MaxInlineLevel=15 -Djava.awt.headless=true -Xlog:gc*:file=/home/kafka/kafka/logs2/kafkaServer-gc.log:time,tags:filecount=10,filesize=100M -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dkafka.logs.dir=/home/kafka/kafka/logs2 -Dlog4j.configuration=file:/home/kafka/kafka/bin/../config/log4j.properties -cp /home/kafka/kafka/bin/../libs/activation-1.1.1.jar:[...]:/home/kafka/kafka/bin/../libs/javassist-3.25.0-GA.jar:/home/kafka/kafka/bin/../libs/javassist-3.26.0-GA.jar:[...] kafka.Kafka /home/kafka/kafka/config/server.properties

There are two versions of javassist library - 3.25.0-GA and 3.26.0-GA.

Should be only one and I believe it should be upgraded to latest version which is 3.27.0-GA.
