Description

We are using BigDecimals in our application quite often for calculating. We store our values typically as java primitives (int, long/double, float) and using the DocumentObjectBinder (annotations based document object binding).

Unfortunately, we must have exactly the type given in solr schema for type used as field/accessor. We found out, that the following patch would allow us to define BigDecimal as type as we just use BigDecimal as a type in our mapped POJO. This would help to make the mapping more powerful without loosing anything.
