Of course, assuming you have a layer of compiled Java (i.e. you are not 
just using J/Link to call library functions), a reasonable alternative 
is to use ReplaceAll to replace the +/- inf values with some impossible 
value (preferably a value with an exact binary representation), and then 
swap the values back again using a loop in the Java.
