Subject [Math] Exceptions from "JDKRandomGenerator"
Date Sat, 19 Dec 2015 16:02:45 GMT
Hi.

While experimenting on
   https://issues.apache.org/jira/browse/MATH-1300
I created a new
   JDKRandomGeneratorTest
that inherits from
   RandomGeneratorAbstractTest
similarly to the classes for testing all the other RNG implemented in 
CM.

The following tests (implemented in the base class) failed:
1. 
testNextIntNeg(org.apache.commons.math4.random.JDKRandomGeneratorTest)  
Time elapsed: 0.001 sec  <<< ERROR!
    java.lang.Exception: Unexpected exception, 
expected<org.apache.commons.math4.exception.MathIllegalArgumentException> 
but was<java.lang.IllegalArgumentException>
2. 
testNextIntIAE2(org.apache.commons.math4.random.JDKRandomGeneratorTest)  
Time elapsed: 0.015 sec  <<< ERROR!
    java.lang.IllegalArgumentException: bound must be positive

This is caused by try/catch clauses that expect a 
"MathIllegalArgumentException"
but "JDKRandomGenerator" extends "java.util.Random" that for those 
methods throws
"IllegalArgumentException".

What to do?


Regards,
Gilles
