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."

But personnally I would prefer to more and more use the JUnit framework. Is there already an existing example?

There's good news on this front. We are in the process of making TestNG a supported test framework for writing unit and regression tests in OpenJDK. TestNG inherits a lot of ideas from JUnit, so JUnit users should find it easy to use, and there are plugins for all the big IDEs. The goal you state -- making it easier to reuse test infrastructure -- is one of the reasons why we want to do this. Another is that many people are already familiar / comfortable with this style of testing, and therefore are more likely to contribute good tests. I don't have a schedule for when this will be supported within the OpenJDK build and test process, but we're working on it. It seems, jtreg to JUnit bridge is already existing: http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2009-October/002003.html

I also have found an example: http://cr.openjdk.java.net/~jrose/6891770/webrev.00/test/java/dyn/MethodHandlesTest.java.html -Ulf
