NumberFormatException on PAPE max_auth_age

[GoogleCodeExporter]

A malformed PAPE request that sends max_auth_age as a non-integer causes 
PapeRequest.getMaxAuthAge() to throw a NumberFormatException , which is not 
declared in the method signature or mentioned in the javadoc.

Should either handle the error internally or make it obvious to API users about 
this behavior.  

Here is how I handle it:

             return -1;
     }
