That was my only use case for the ConstantContinuousDistribution. It appears to be a strange addition to the library. No other libraries I looked at have it. A bit of digging in the commit history of CM found that this distribution was added to fix MATH-984 [1] so the EmpericalDistribution can represent each bin using a distribution that can perform sampling of the bin. If a bin has a single value then the ConstantContinuousDistribution applies. Since this does not apply to the code in Commons statistics then I would suggest dropping it from the library.
