What steps will reproduce the problem?
1. Follow readme.txt and run the example FastDtwTest with Euclidean and 
Manhattan distances
2. Warping distances are identical
3. Try different data sets

What is the expected output? What do you see instead?

I expect the 2 distances to be different.

What version of the product are you using? On what operating system?

1.1.0

Please provide any additional information below.

The error appears to be in com.util package and the ManhattanDistance and 
EuclideanDistance classes. Although the formulas are correct the 2 methods are 
invoked for vectors containing single points, hence the inner loops are 
computing the absolute difference (Manhattan distance) because the comparison 
is always between 2 points. 

-- What steps will reproduce the problem?
1. Unzip the archive with the Windows 7 built-in unzipper

What is the expected output? What do you see instead?
Files should be listed as unencrypted.  Instead, they are unpacked with the 
"encrypted" bit and are colored green in the file listing.

-- What version of the product are you using? On what operating system?
Windows 7 x64 Ultimate

It's not your fault!  It's a Windows bug...

Still, I wonder if there's any way to prevent it...

https://github.com/medined/fastdtw - I've moved the files into the maven 
standard directories and added a pom.xml file.
