Denis Golovin commented on JBDS-2880:
-------------------------------------

EclipseGenerator is empty application, it does nothing just starts and exits, but calling this application triggers initialization for eclipse platform. For example OSGi cache is filled and so on (I didn't really look into other details). Next time eclipse starts faster, because initialization is done at installation time.

You can try on any eclipse package:
# Unpack eclipse
# Start it and watch delay between two events: splash is shown and workspace location dialog is shown
# Hit Cancel
# Start eclipse again and you see delay between splash and workspace location dialog is shorter.

Delay at (2) was really long in eclipse at some point, so we had to do that tick.  Now it is much faster but still noticeable.
