Alfresco has explicit special handling for date properties. Since it is very unlikely someone would be searching on an exact timestamp, Alfresco support a date-based condition to be a map with the following allowed entries:

key: DatePosition.BEFORE, value: date value compared against using less or equals
key: DatePosition.AFTER, value: date value compared against using greater or equals

You can see that by looking at the source of the class referenced by the error stacktrace.

Yes, Many thanks ! Code below is working fine:

WorkflowInstanceQuery workflowInstanceQuery = new WorkflowInstanceQuery();
Map<QName, Object> filters = new HashMap<QName, Object>;

Map<DatePosition, Date> dateParams = new HashMap<DatePosition, Date>();

dateParams.put(DatePosition.BEFORE, endRangeDate);

dateParams.put(DatePosition.AFTER, startRangeDate);

filters.put(propertyQName, dateParams);
workflowInstanceQuery.setCustomProps(filters);
this.workflowService.getWorkflows(workflowInstanceQuery, maxItems, skipCount);
