If different ranges of s2 and s3 are being used in different test loops, it seems like it would be easier to follow if you broke up the ranges into different String[] variables and indexed them with a negative offset from "i" where you had to.

It's hard to tell if there is some distinction that puts some values in some section of s2 and others in some section of s3.

Would it be possible to give these variables s2/s3 more meaningful names that explain what you are testing.
