A clean way to copy directory contents between different file systems?

Question

I want to copy files from one java.nio.file.FileSystem to another one. For example, from default file system to com.google.common.jimfs.Jimfs.

I've written some utility classes for this use case. The library is Open Source, maybe you find it useful:

CopyFileVisitor.copy(srcPath, targetPath);  

Maven:

<dependency>
    <groupId>org.softsmithy.lib</groupId>
    <artifactId>softsmithy-lib-core</artifactId>
    <version>0.5</version>
</dependency>
