---------------------------------

             Summary: Error serializing BigDecimal when passed certain BigDecimal values
                 Key: OLINGO-1568
                 URL: https://issues.apache.org/jira/browse/OLINGO-1568
             Project: Olingo
          Issue Type: Bug
          Components: odata4-client
    Affects Versions: (Java) V4 4.9.0, (Java) V4 4.8.0
            Reporter: Victor Hu


This is a refiling OLINGO-1549 except categorized as a bug.

This bug was introduced with the change made in OLINGO-1480 to allow for larger precision/scale values when passed in as a BigDecimal as they can exceed the default precision of 40 and scale of 25.

However, this broke insertions for values ranging from ]0.0, 0.1[ as their BigDecimal representations have precision less than scale (which is not allowed according to the [OData CSDL|http://docs.oasis-open.org/odata/odata-csdl-json/v4.01/odata-csdl-json-v4.01.html#sec_Scale]).

This also breaks insertions for BigDecimal values that do not specify precision - an arbitrary precision in BigDecimal is represented as 0 versus the arbitrary precision representation of null in OData.



The following throws an exception due to this bug
{code:java}
new ClientObjectFactoryImpl().newPrimitiveValueBuilder().buildDecimal(new BigDecimal("0.04")).toString();
{code}
{noformat}
java.lang.IllegalArgumentException: org.apache.olingo.commons.api.edm.EdmPrimitiveTypeException: The value '0.04' does not match the facets' constraints.{noformat}
