I created .war by using
gradlew bootJar and manually deploy to Tomcat 9.0.16. However when I deleted war and Tomcat failed to delete the exploded folder. Logs are:
scratch_6.log (15.0 KB)
It seems some threads in thread pool are not stopped. Their names are
pool-4-thread-1,core-1, core-2, ui_backgroundScheduler1, core-3.
Note: Database mysql and oracle produce same problem. CUBA doesn’t has this problem.
