> Right now there are 2 optimizer implementations, only one of which is ever loaded. The
other implementation was disabled by the following comment in modules.properties:
> # use level1 optimizer for small configurations
> #
> # can't do this in the codeline because with 2 implementations, it is entirely
> # by chance which get picked.  So we may be running with different modules
> # depending on which jdk
> #
> # to be resolve by Siuling and Dan
> #
> #derby.module.optimizerSmall=org.apache.derby.impl.sql.compile.OptimizerFactoryImpl
> #cloudscape.config.optimizerSmall=cloud,cloudtarget
> Since we have deprecated support for the small CDC configuration, I don't think that
we need further resolution by Siuling and Dan. Collapsing the two optimizers together should
slightly reduce our static footprint.
