mapping order impacting behavior leading to bug
-----------------------------------------------

                 Key: HHH-4825
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4825
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.2
            Reporter: Anthony Patricio


Following mapping fails:

<hibernate-mapping default-access="property" package="case419703">

<class abstract="false" dynamic-insert="true" dynamic-update="true" name="TestB"
      table="TEST_B">
    <composite-id class="case419703.key.FrameworkKeyCustID"
        name="frameworkKey">
      <key-property column="NR_RZBK" name="frameworkCustId"/>
      <key-property column="TXT_OID" name="frameworkOid"/>
    </composite-id>
    <version column="NR_VERSION" name="frameworkVersion"/>

    <set cascade="persist, merge, save-update" inverse="true" lazy="true" name="testC">
      <key>
        <column name="NR_RZBK"/>
        <column name="TXT_OID_TESTB"/>
      </key>
      <one-to-many class="TestC"/>
    </set>
  </class>

<class abstract="true" dynamic-insert="true" dynamic-update="true" name="AbstractTestC"
      table="notable">
    <composite-id class="case419703.key.FrameworkKeyCustID"
        name="frameworkKey">
      <key-property column="NR_RZBK" name="frameworkCustId"/>
      <key-property column="TXT_OID" name="frameworkOid"/>
    </composite-id>
    <version column="NR_VERSION" name="frameworkVersion"/>

    <union-subclass dynamic-insert="true" dynamic-update="true" name="case419703.TestC"
        table="TEST_C">
      <property column="PID" name="pid" update="false"/>
      <property column="TXT_OID_TESTB" name="fkReverseTestB"/>
      <many-to-one cascade="persist, merge, save-update" class="case419703.TestB"
          fetch="select" insert="false" lazy="no-proxy" name="reverseTestB" 
          update="false" >
        <column name="NR_RZBK" />
        <column name="TXT_OID_TESTB" />
        <!-- formula>'TXT_OID_TESTB'</formula-->
      </many-to-one>
    </union-subclass>
  </class>
</hibernate-mapping>

however changing to

      <many-to-one cascade="persist, merge, save-update" class="case419703.TestB"
          fetch="select" insert="false" lazy="no-proxy" name="reverseTestB" 
          update="false" >
        <column name="NR_RZBK" />
        <column name="TXT_OID_TESTB" />
        <!-- formula>'TXT_OID_TESTB'</formula-->
      </many-to-one>
      <property column="PID" name="pid" update="false"/>
      <property column="TXT_OID_TESTB" name="fkReverseTestB"/>
works.

Something is wrong with th algo.
See attached testcase.
