A DESCRIPTION OF THE PROBLEM :
the class is a helper for variable row-height in JTable. To perform some search, it computes the mid of some intervall using the expression
        int mid = (from + to) / 2; // there are 6 occurences of this in the class
this is prone to intermeditate integer-overflow (the classical error in binary search).
the expression should be written as
       int mid = (from + to ) >>> 1;
as in other places in the JDK.


CUSTOMER SUBMITTED WORKAROUND :
keep the JTables small enough
