Seeding a default RNG
---------------------
Key: MATH-701
URL: https://issues.apache.org/jira/browse/MATH-701
Project: Commons Math
Issue Type: Bug
Reporter: Gilles
Assignee: Gilles
Fix For: 3.0
In "RandomDataImpl":
{code}
private RandomGenerator getRan() {
if (rand == null) {
rand = new JDKRandomGenerator();
rand.setSeed(System.currentTimeMillis());
}
return rand;
}
{code}
The conditional branch is used by "sample()" in
"AbstractContinuousDistribution".
When several "...Distribution" objects are instantiated in a short time
interval, they are seeded with the same value.
