P3 Description
FULL PRODUCT VERSION :
java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.3.9600]
A DESCRIPTION OF THE PROBLEM :
I'm the developer and maintainer of the javafx-gradle-plugin.
While creating support for the daemon-mode of gradle, some user reported that the clean-task wasn't successful. After some deeper research I found out, that there is a file handle open to the bin-folder inside the copied RUNTIME.
When copying the microsoft runtime DLLs, the stream returned by Files.list() isn't closed resulting to a still open file handle. That file handle stays open, because the JVM is not stopped and the handle isn't closed.
I have searched for that problem and I might have found it here:

"As this stream is a DirectoryStream (as documented), this should have to be closed, mostly by using try(resouce){}-syntax."
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No file handle on the runtime/bin-folder
REPRODUCIBILITY :
This bug can be reproduced always.
