We are encountering the same issue (also due to our use of the embedded-elasticsearch plugin) We can also reproduce the situation in this library by running mvn clean build with JDK 11.

It seems to me that a fix could be to use java.nio to set file permissions instead.

I would be glad to provide to provide pull requests.
Maybe something based on #66?
