I've fixed this in the 2.1 branch. I don't think its worth doing the fix for 2.0 branch .... the workaround is very easy: add a cascade="none" to the array mapping (the XML parser will complain, but it will work).

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-250
    Summary: Cascade onto primitive-array
       Type: Bug

     Status: Closed
   Priority: Minor
 Resolution: FIXED

    Project: Hibernate2
   Fix Fors:
             2.1 beta 2

   Assignee: 
   Reporter: Teradyne Inc.

Environment: Windows XP Pro
Java 1.4.1_02
MySQL 4.0.13-nt

Description:
If class: 

public class Foo
{
private int[] exponents;
public Foo() {}
public int[] getExponents()
{
return exponents;
}
public void setExponents(int[] exps)
{
this.exponents = exps;
}
}


Is mapped with the following ..hbm.xml:

<hibernate-mapping default-cascade="save-update">
<class name="Foo" table="foos">
<id column="id" type="int">
<generator class="native" />
</id>
<primitive-array name="exponents" >
<key/>
<index/>
<element type="integer"/>
</primitive-array>
</class>
</hibernate-mapping>

It causes the following error:

java.lang.ClassCastException
at net.sf.hibernate.type.ArrayType.getElementsIterator(ArrayType.java:42)
at net.sf.hibernate.engine.Cascades.cascade(Cascades.java:276)
at net.sf.hibernate.engine.Cascades.cascade(Cascades.java:341)

at net.sf.hibernate.impl.SessionImpl.saveOrUpdate(SessionImpl.java:1213)
at net.sf.hibernate.engine.Cascades$3.cascade(Cascades.java:88)

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

This method should only be called if you enable cascade for that collection (which makes no sense for a primitive array).
