Feedback on the quality and stability of development builds is of course key to any software development project. Oracle Quality Engineering Manager Rory O'Donnell has taken a first hit at making test results for the JDK 8 early access builds available, you can find them on the project page: http://jdk8.java.net/.
Rory announced this is in a post to the OpenJDK quality-discuss mailing list, might be interesting to follow!
