Logback throwing ConcurrentModificationException on exiting program inside docker container

Question

My application is throwing ConcurrentModificationException when it is trying to exit the program.It is using a standard Logback configuration. This works fine when running as a standalone java application but throws the exception when trying to run inside a docker container. The stack trace is as below:

Exception in thread "Logback shutdown hook [default]" java.util.ConcurrentModificationException
    at java.base/java.util.ArrayList$Itr.checkForComodification(ArrayList.java:1043)
    at java.base/java.util.ArrayList$Itr.next(ArrayList.java:997)
    at ch.qos.logback.classic.LoggerContext.fireOnReset(LoggerContext.java:323)
    at ch.qos.logback.classic.LoggerContext.reset(LoggerContext.java:226)
    at ch.qos.logback.classic.LoggerContext.stop(LoggerContext.java:348)
    at ch.qos.logback.core.hook.ShutdownHookBase.stop(ShutdownHookBase.java:39)
    at ch.qos.logback.core.hook.DelayingShutdownHook.run(DelayingShutdownHook.java:57)
    at java.base/java.lang.Thread.run(Thread.java:834)

I am using a standard Logback configuration file through logback-spring.xml
