Description

I built a wikipedia index, with multiple fields for faceting.

When I do facet.method=fcs with facet.field=dateFacet and facet.field=userNameFacet, and then kill -QUIT the java process, I see a bunch (46, I think) of facetExecutor-7-thread-N threads had spun up.

But I thought threads for each field is turned off by default?

Even if I add facet.threads=0, it still spins up all the threads.

I think something is wrong in SimpleFacets.parseParams; somehow, that method returns early (because localParams) is null, leaving threads=-1, and then the later code that would have set threads to 0 never runs.
