             Summary: MathInternalError when calculating barycenter of PolyhedronsSet
                 Key: MATH-1060
                 URL: https://issues.apache.org/jira/browse/MATH-1060
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.2
         Environment: Ubuntu, Java 1.7.0
            Reporter: Ian Perera


I'm not sure if I could replicate this well enough to be useful - I am trying to construct a PolyhedronsSet from a collection of Planes using RegionFactory.buildConvex(). The input planes are created from running QHull - I don't have the actual normals but I can add them to this report if I run into this again.

Exception in thread "KQML-Dispatcher-1" org.apache.commons.math3.exception.MathInternalError: illegal state: internal error, please fill a bug report at https://issues.apache.org/jira/browse/MATH
