The conclusion from [1] was never implemented and I was, once again, confused by these properties when developing some density integration tests last night. I would like to deprecate these properties from the RealDistribution interface, but since removal will have to wait until 4.0, I would like to agree on a precise definition and fix the code to match it in the mean time.
The definition that I propose is that isSupportXxxInclusive means that when the density function is applied to the upper or lower bound of support returned by getSupportXxxBound, a finite (i.e. not infinite), not NaN value is returned. The code is now consistent with this definition other than for the F distribution, where the lower bound of support is marked included but the density returns NaN there. If others are in agreement, I will make the deprecations, clarify the javadoc, change the value returned by FDistribution to match the contract and add tests.
