Using FileSystem closes all the ressources when using an URLClassLoader

[adrien-aubert-drovio]

Version

4.5.1

Context

When deploying a verticle using an URLClassLoader (when loading classes from a JAR file), using the vertx.fileSystem() to read files/directories will close the opened resources related to the JAR file once the operation completes. For example, if an InputStream is opened to read a file from the JAR file, the InputStream will be closed as well, even if it is still in use.

There is no problem with version 4.4.6 of Vertx.

Do you have a reproducer?
