Robert Muir commented on SOLR-2802:
-----------------------------------
I think the min/max is strange: it catches ClassCastException (as hoss
explained on dev list):
{noformat}
* If this is not the case, then the full list of all values found will be
* used as is.
{noformat}
In my opinion, I think if a user asks for min or max or some other computation,
and this is not possible,
it should return an error? otherwise why did they configure this in their
chain?
I don't think its friendly to just sneakily act as a no-op instead...
Moreover, the root cause of the eclipse-compiler problems I think is because
its not taking Comparable?
I think min/max should not extend this type-unsafe Subset base, as they should
not return a subset anyway,
but a singleton, and the input must be comparable...
