Re: Re[2]: [equinox-dev] About the benchmarks of OSGi

Yes but the resolver etc is more complicated
and takes more work.  What you are calling esoteric may well be main
line for Eclipse (and vice versa).  Pascal'point is very apt.  If
you are measuring startup and footprint the R4 changes likely play a role.
 In any event, implementations should stand on their merits/behaviour.
 The scale factor should not be underestimated also.  Eclipse
has been optimized to run 1000s (yes, 3 zeros) of bundles.  Our footprint
might be larger to start but in larger systems we are smaller and faster.

Subject	Re[2]: [equinox-dev] About the benchmarks of OSGi

R3 are still compatible with R4. R4 added some new
class loading features but they are mostly in the more esoteric range
for large deployments that do not want to refactor their code.

R3 bundles are still more or less the preferred mode and run unchanged
on R4 frameworks.

Kind regards,
