Description

The MapFile.Reader getClosest() method returns incorrect results due to an error in seekInternal(). The test case in trunk sets the index interval of the test MapFile to 1 which obscures the issue. There are several other errors in the test case as well that assert incorrect behavior for getClosest().

I've got this fixed and tested, and will attach a patch.
