Hi, Eric.
Try to add to Tomcat’s JVM_OPTS following directives, please:
--add-exports java.base/jdk.internal.misc=ALL-UNNAMED
--add-exports java.base/sun.nio.ch=ALL-UNNAMED
--add-exports java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED
--add-exports jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED
--add-modules java.xml.bind
