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.

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,
