From Josh Bloch:

Double.MIN_VALUE and Float.MIN_VALUE do not actually provide the minimum double or float values. Instead, they provide the smallest positive nonzero value of the given type.

This is confusing, since Integer.MIN_VALUE behaves differently, and therefore most uses of Double/Float.MIN_VALUE are probably bugs.
