ADDITIONAL SYSTEM INFORMATION :
OS: Microsoft Windows 10 Enterprise
Java: 1.8.0_232

A DESCRIPTION OF THE PROBLEM :
Calling java.nio.file.Files.copy(Path, Path, CopyOption...) using long filenames (more than 256 characters?) results in JVM exits.
The problem is related to windows device path, ones starting with "\\?\"

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Call java.nio.file.Files.copy(Path, Path, CopyOption...) with a long filename in "target" parameter

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
File copied to destination.
In the attached example, it is expected to print: "prepare to copy" and "copy OK" but the latter is not.

ACTUAL -
JVM exits
