Quartz Scheduler not stopping after shutdown

Please try to apply with these configuration when init scheduler

org.quartz.threadPool.makeThreadsDaemons=true
org.quartz.scheduler.makeSchedulerThreadDaemon=true
org.quartz.scheduler.interruptJobsOnShutdown=true
org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true

You can refer to this link for more detail: https://www.techpaste.com/2016/03/quartz-scheduler-shutdown/

If there are any jobs executing when you call shutdown, whether to interrupt those jobs or not depends on the property org.quartz.scheduler.interruptJobsOnShutdown.

See http://jira.terracotta.org/jira/browse/QTZ-41?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel . I am unable to find more documentation on this.

The other property is org.quartz.scheduler.makeSchedulerThreadDaemon=true, which will shutdown quartz scheduler as soon as your calling thread shuts down. I do not know what happens to the state of the jobs.

As mentioned in the comments, post some code and configuration to get clear answer.

you can use org.quartz.plugin.shutdownhook.cleanShutdown=TRUE in your quartz properties file
