jtreg, junit, and testng (was Re: Request for review : 7121314 : Behavior mismatch between AbstractCollection.toArray(T[] ) and its spec)

[Brian Goetz]

The primary reason is: Oracle has internal processes that we must follow 
to use third-party software in our products (whether open-source or 
closed-source products, and whether or not the third-party software is 
ultimately distributed with the product or not.)  An examination of the 
TestNG license compared to the JUnit license suggested that it was going 
to be significantly easier to obtain the required internal approvals for 
TestNG.

Since TestNG is also pretty good (one could argue which is better, and 
there are pros and cons on both sides of this argument, but its clearly 
"good enough"), we chose the path of "let's get something done."
