Answer Short answer: yes, it closes the stream. Slightly

Apache Commons IO File Monitoring vs. JDK WatchService

apache-commons-io file-processing java watchservice

I need to develop an application that will process csv files as soon as the files are created in a predefined directory. Huge number of incoming files is expected.
