Hello!
I am currently moving from solr version 6.3.0 to solr version 8.11.1. I am
using java 8(jdk1.8.0_272).
When using the following command:
java -Xms4196m -Xmx7168m -verbose:gc -XX:NewRatio=3 -XX:SurvivorRatio=4
-XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=8 -XX:ConcGCThreads=4
-XX:ParallelGCThreads=4 -XX:+CMSScavengeBeforeRemark
-XX:PretenureSizeThreshold=64m -XX:+UseCMSInitiatingOccupancyOnly
-XX:CMSInitiatingOccupancyFraction=50 -XX:CMSMaxAbortablePrecleanTime=6000
-XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled
-XX:-OmitStackTraceInFastThrow -DSTOP.PORT=7983 -DSTOP.KEY=mysecret

-Dsolr.jetty.https.port=8983 "-Djetty.home=C:\Program Files\Morphisec

"-Dsolr.log.dir=C:\Program Files\Morphisec Server\solr-8.11.1\server\logs"
-Dsolr.autoCommit.maxTime=60000 -Dsolr.ssl.checkPeerName=false
"-Djavax.net.ssl.trustStore=C:\Program Files\Morphisec
Server\solr-8.11.1\server\etc\keystore.solr.jks"
-Djavax.net.ssl.trustStorePassword=DEA7B39145F6478C -DzkClientTimeout=15000
-DzkRun -jar start.jar --module=https -DurlScheme=https
I am receiving the following exception:
ClassNotFoundException:

I found out that the issue was with the jetty-ssl.xml file which was
changed from version 6.3.0.
When replacing the file to the previous version and trying to execute the
command, I am receiving a different error:
Caused by: java.lang.IllegalStateException: No Server ALPNProcessors!
at
org.eclipse.jetty.alpn.server.ALPNServerConnectionFactory.<init>(ALPNServerConnectionFactory.java:52)
... 35 more
Suppressed: java.lang.UnsupportedClassVersionError:
org/eclipse/jetty/alpn/java/server/JDK9ServerALPNProcessor has been
compiled by a more recent version of the Java Runtime (class file version
53.0), this version of the Java Runtime only recognizes class file versions
up to 52.0
After google search I found that the file that is being used doesn't fit to
java 8, when downloading the jar
"jetty-alpn-openjdk8-server-9.4.44.v20210927.jar" and adding it to
"server/lib", it works.
thank you
