Hi Ken, That does indeed help.
I'm guessing that "org.eclipse.equinox.common" and "org.eclipse.osgi" bundle dependencies suggest that JFace has implementation-specific dependencies (using utility classes packaged with framework implementation). I've tried some quick searching and the best I could find is http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Foverview-summary.htmlwhich suggests that if I'm interested in using JFace, I need to add dependencies for SWT (per platform) and the Eclipse RCP. Hope it doesn't turn out to consume a disproportionate amount of storage space/download time. Incidentally, another reason for me evaluating all this stuff is that -- as Linux GTK is a target -- getting something reasonable on Linux (as Swing GTK isn't great for font rendering, and Linux/JavaFX doesn't seem a priority for Oracle). Will try that out then.
