> When indexing map fields that have null keys, geode throws an NPE.
> Steps to reproduce:
> 1. Create an index on a map field eg
> {code}
> create index --name="idx_positions" --expression="positions[*]" --region="region"
> {code}
> 2. Add entries with null keys in the the indexed map
> {code}
> entry.positions  = new HashMap()
> entry.positions.put(null, "somevalue);
> region.put(entry);
> {code}
> You will get an NPE
> {noformat}
> Caused by: java.lang.NullPointerException
