finally toward end following

ps:

this causing issue in intellij. indeed, can still start , stop terminal tomcat. however, within intellij following on restart:

error: exception thrown agent : java.rmi.server.exportexception: port in use: 1099; nested exception is: java.net.bindexception: address in use

i have kill process on 1099 every time restart within intellij.
