Hello. I'm having problems when I try to send a GET request using the CSW
interface. If I use a spatial filter, GetRecords request returns an empty
result, and the following information appears in the logs:

I can not understand, why the filter contains this text string after
<ogc:Crosses>: [ the_geom crosses POLYGON ((105.2246 17.0453, 105.2246
56.0162, 183.9746 56.0162, 183.9746 17.0453, 105.2246 17.0453)) ]
If I use search by date, then everything works fine. I used different
versions of GeoNetwork and each time I got the same result.

Example of request:

http://localhost:8080/geonetwork/srv/eng/csw?OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&STARTPOSITION=1&MAXRECORDS=10&REQUEST=GetRecords&RESULTTYPE=results&SORTBY=Date:A&VERSION=2.0.2&TYPENAMES=gmd:MD_Metadata&ELEMENTSETNAME=full&SERVICE=CSW&CONSTRAINTLANGUAGE=CQL_TEXT&CONSTRAINT_LANGUAGE_VERSION=1.1.0&CONSTRAINT=Date
> '2000-01-01T00:00:00Z' and Date < '2017-07-16T14:00:00Z' and
(CROSSES(the_geom, POLYGON((105.2246 17.0453, 105.2246 56.0162, 183.9746
56.0162, 183.9746 17.0453, 105.2246 17.0453))))

Thank you in advance.
