I try to create a new zip file using FileSystems.newFileSystem(URI, Map, null).
In Map it contains <"create", "true">. And run it in windows.

The method throws below exception, not sure whether it is a bug:
========================================
java.lang.IllegalArgumentException: Path component should be '/'
at sun.nio.fs.WindowsFileSystemProvider.checkUri(WindowsFileSystemProvider.java:68)
at sun.nio.fs.WindowsFileSystemProvider.newFileSystem(WindowsFileSystemProvider.java:79)
at java.nio.file.FileSystems.newFileSystem(FileSystems.java:322)
at ZipfsNewFileSystem.main(ZipfsNewFileSystem.java:25)
file:///D:/workspace/zipfs/nosuchfile.zip
========================================

My test code is below:
========================================
import static TestUtils.TestTasks.*;
import java.nio.file.FileSystems;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.*;
import com.sun.nio.zipfs.ZipFileSystem;

// Basic newFileSystem test for zip file
// Test environment variable: createNew
public class ZipfsNewFileSystem {

private static final String nonExistentFile = "nosuchfile.zip";

public static void main(String[] args) throws Exception {

        Path file = Paths.get(nonExistentFile);
Files.deleteIfExists(Paths.get(nonExistentFile)) ;

        Map<String, String> env = new HashMap<String, String>();
        env.put("create", "true");
        file = Paths.get(nonExistentFile);
try {
System.out.println(file.toUri()) ;
ZipFileSystem fs = (ZipFileSystem)FileSystems.newFileSystem(file.toUri(), env, null) ;
            // close now so the zip file gets flushed
            fs.close();
if (!Files.deleteIfExists(Paths.get(nonExistentFile))) {
throw new RuntimeException(nonExistentFile + "should have been created!");
}
} catch (Exception e) {
e.printStackTrace() ;
}

}

}
