Problem with layer.getExtent() and Oracle (MapScript Java)

[Arkadi Shishlov]

Calling extent = layer.getExtent() on the Oracle based layer returns rectObj with all components set to -1
extent => { 'minx': -1 , 'miny': -1 , 'maxx': -1 , 'maxy': -1 }

The layer is created by

sqlMapserverQuery = "L82GEOMETRY from (select null, L82GEOMETRY, DATASET82ID, L82C23T1, L82C12T1, L82C20T1, L82C24T1, L82C22T1, L82C21T1 from DATASET82 where 1 = 1) USING UNIQUE DATASET82ID SRID 3059"

layer.setStatus(mapscriptConstants.MS_ON);
//layer.setType(MS_LAYER_TYPE.MS_LAYER_ANNOTATION);
layer.setType(MS_LAYER_TYPE.MS_LAYER_POINT);
layer.setConnectiontype(MS_CONNECTION_TYPE.MS_ORACLESPATIAL);
layer.setConnection(mapDataConnectionString);
layer.setData(sqlMapserverQuery);
layer.setStatus(visible ? 1 : 0);
layer.setTemplate("any.html");
layer.setProjection(dbProjection);

I can sucessfully retrieve extent of SHP based layers. Also many other operations on the above mentioned Oracle layer works just fine.
I'm using Mapserver 4.10.1 from MS4W 2.2.3 on Windows XP, Sun Java 1.5.0_09, Tomcat 5.5.20.
Any hints? Is it a bug in my application or Mapserver?
