Also, this email distribution list is still pretty light... People have to be added explicitly... When I signed up this morning, there were only 3 people on the list. That is probably you, me, and Dmitry... Not a large contingent yet. So, we can't count a lack of responses as non-caring.
Have to love your enthusiasm though! But, we probably have to cut back on the throttle a bit... The number one priority of the EE4J project is to ensure we're compatible with Java EE 8. The code that Oracle is contributing to Eclipse needs to pass all of the Java EE 8 compatibility tests, known as the CTS. This test suite is comprised of somewhere around 45,000 tests.
So, we need to be careful on what type of changes are being put into the github repository at this point. The move to Eclipse is still new to a few people and we need to wait for a bit more participation before we make too many changes. If there are developers from the old Expert Group that need to subscribe and participate, please encourage them. Eclipse is a very open and welcoming community. It should be very easy for any developer to sign up without issue.
