Yesterday Michael Keppler commented on my latest blog post the following:
Although the general process for contributions has improved, there is still quite a difference between what a single _committer_ can do, and what a single _contributor_ can do. It is frustrating if you create bug reports or patches, and no one looks at them. As a (non committer) contributor, you still very much depend on project committers, and their time is a scarce resource. Therefore, from the outside it does not look that easy to me as described by you.
I assume Michael is referring to patches in Bugzilla. The platform.ui team (and I believe the JDT team also) is IMHO good in reviewing Gerrit contributions. I agree that patches in Bugzilla tend to get ignored, I was no one has the time to find and review them.
So please convert any patch you have to a Gerrit review. See Eclipse platform contributions for a description of the required setup.
