Hi,
I'm trying to update from hibernate 5.2.18 to 5.4.4 and I'm facing a regression with a type in CompositeUserType that hibernate can't handle.
To simplify my problem, I have the following “{{Population”}}entity, containing a non entity “{{Matrix” object:}}
{code:java}// Some comments here
public class Population {
public Matrix effective;
}{code}
And the following xml mapping:
{code:xml}<?xml version="1.0" encoding="UTF-8"?>
<hibernate-mapping xmlns="http://www.hibernate.org/xsd/hibernate-mapping"
xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-mapping classpath://org/hibernate/hibernate-mapping-4.0.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
default-access="field" auto-import="true" package="fr.mycompany.mypackage">
<class name="fr.mycompany.mypackage.entities.Population" table="population" abstract="false">
<property name=" recruitmentDistribution effective " access="field" type="fr.mycompany.mypackage.types.hibernate.MatrixType">
<column name="effective_name"/>
<column name="effective_dim"/>
<column name="effective_dimNames"/>
<column name="effective_semantics"/>
<column name="effective_data"/>
</property>
</class>
</hibernate-mapping>{code}
“Matrix” object can be resumed as:
{code:java}public class Matrix {
protected String name;
protected List<String> dimNames;
protected List<?>[] semantics;
protected Object data;
}{code}
Since, update, hibernate complains about a strange type into 'Matrix' object : java.util.List<?>\[]
It's ok, that hibernate can't handle that, but why does hibernate throw the following error for *a field inside a CompositeUserType* ?
{code:java}java.lang.IllegalArgumentException: No PropertyTypeExtractor available for type void
