unpack-dependencies fails on Windows for a tar.gz dependency containing an executable file with the following message:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.10:unpack-dependencies (unpa
ck-jres) on project boxfuse-commandline: Error unpacking file: C:\Users\Axel\.m2\repository\com\oracle\server-

This was working fine in all previous versions including 2.8 and 2.9

Start with the attached pom.xml and the unpack-dependencies goal, then reproduce the failure on Windows using the tar.gz dependency containing the executable file described in the report. The work is done when that dependency unpacks successfully on Windows without the privilege error and existing behavior for earlier plugin versions remains intact.
