NPE from JDBCControl when method returns XMLBeans Document type
---------------------------------------------------------------

                 Key: BEEHIVE-1153
                 URL: http://issues.apache.org/jira/browse/BEEHIVE-1153
             Project: Beehive
          Issue Type: Bug
          Components: System Controls
    Affects Versions: 1.0.1, 1.0, v1m1, V1Beta, V1Alpha, 1.0.2
            Reporter: Chad Schoettger

When a JDBCControl method returns a XMLBeans Document type, an NPE is thrown.

Sample Schema:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="java:///database/customer_db" xmlns="java:///database/customer_db"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
  <xsd:element name="XCustomer" wld:DefaultNamespace="java:///database/customer_db">
    <xsd:complexType>
      <xsd:choice maxOccurs="unbounded">
        <xsd:element name="XCustomerRow">
          <xsd:complexType>
            <xsd:sequence>
              <xsd:element name="CUSTID" type="xsd:int" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="NAME" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="ADDRESS" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="CITY" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="STATE" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="ZIP" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="AREA_CODE" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
              <xsd:element name="PHONE" type="xsd:string" minOccurs="0" nillable="true"></xsd:element>
            </xsd:sequence>
          </xsd:complexType>
        </xsd:element>
      </xsd:choice>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

Sample JDBCControl Method:

  @JdbcControl.SQL(statement = "SELECT custid, name, address, city, state, zip, area_code,
phone FROM customer WHERE custid = {key}")
    public XCustomerDocument getCustomerByID(int key);
