[lispercat]

My JDK version: OpenJDK 13.0.1

My Operating System (Linux/OSX/Windows X/Other): Windows 10

Stacktrace (if applicable):

Debugger entered--Lisp error: (file-error "Removing directory" "Permission denied" "c:/Users/me/AppData/Local/Temp/JDEE_flycheck_qpYCUh")

jdee-flycheck-cleanup()
kill-buffer(#<buffer Test.java<2>>)

How to reproduce (if applicable):

1. Install jdee package from melpa
2. put following configuration in init.el
   (use-package jdee
   :ensure t
   :init (progn
   (setq jdee-jdk-registry (quote (("13.0.1" . "C:/jdk-13.0.1"))))
   (setq jdee-flycheck-enable-p t)
   (setq jdee-server-dir "C:\Users\me\.m2\repository\com\github\jdee-emacs\jdee-server\1.1-SNAPSHOT")))
3. Open an existing *.java file

Other info you consider could help to fix it:

When flycheck is enabled and when I try to open a *.java file it complains that it can't delete a temporary folder like "c:/Users/me/AppData/Local/Temp/JDEE_flycheck_qpYCUh"
Disabling filecheck fixes the problem.
The reason why it can't delete is is because javaw.exe still holds it
