I am one of the founding committers of Eclipse. (The founding committers are the original team at OTI who started the project and wrote the original code before turning it into Open Source, before the community process was established). My role was that I made the Linux (GTK) port. (I also contributed in some areas other than the Linux port, but those contributions are much less fundamental and/or interesting).
The work on Eclipse SWT and its Linux port, continues directly from my work on Squeak Cheese and other applications of FFI to integrated Native/Interpretive UI.
