This definitely does not apply to me. For free-software products developed by Sun I've had issues with (Hudson, OpenGrok, VirtualBox; never needed to be involved with MySQL or Java communities), the Sun engineers were always very kind, responsive and overly helpful. All of those are perfectly maintained and have prospering communities.
An example of outstanding care of a Sun engineer for the community comes to my mind; once a VirtualBox developer analysed and fixed an issue with RPM Fusion-packaged VirtualBox-OSE directly on my machine as the kernel core dump was too big for me to upload. Without me having paid for support.
