org.hibernate.ejb.AbstractQueryImpl#registerParameterBinding throws ClassCastException if
the parameter value is a primitive type array.
----------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-5292
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5292
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager
Affects Versions: 3.5.1
Environment: Hibernate 3.5.1, HSQL 1.8
Reporter: Jürgen Kellerer
When I set a query paramter on a TypedQuery that is a primitive array (in my case byte[])
there will be a ClassCastException inside the method
org.hibernate.ejb.AbstractQueryImpl#registerParameterBinding because the method tries to
cast byte[] to Object[]:
{noformat}
... else if (value.getClass().isArray()) {
final Object[] array = (Object[]) value;
...
{noformat}
*Produces:*
{noformat}
java.lang.ClassCastException: [B cannot be cast to [Ljava.lang.Object;

{noformat}
*Reproduction is easy:*
{noformat}
em.createQuery("SELECT e.stringValue FROM entity e WHERE e.guid = :guid",
String.class).setParameter("guid", new byte[16]);
{noformat}
having entity defined as:
{noformat}
@Entity(name = "entity")
public class Entity {
@Column(length=16)
byte[] guid;
@Column
String stringValue;
}
{noformat}
*Solution:*
The solution to the problem is quite simple. By checking list types only if the direct
type match doesn't return true, the system doesn't have such an issue. The
following patch fixes the bug:
Patch for the method inside org.hibernate.ejb.AbstractQueryImpl.java[274]:
{noformat}
protected void registerParameterBinding(Parameter parameter, Object value) {
final Class<?> targetType = parameter.getParameterType();
if ( value != null && targetType != null ) {
if (!targetType.isInstance(value)) {
if ( Collection.class.isInstance( value ) ) {
final Collection collection = (Collection) value;
// validate the elements...
for ( Object element : collection ) {
if ( ! targetType.isInstance( element ) ) {
throw new IllegalArgumentException(
"Parameter value [" + element + "] was not matching type [" +
targetType.getName() + "]"
);
}
}
} else if ( value.getClass().isArray() ) {
final Object[] array = (Object[]) value;
for ( Object element : array ) {
if ( ! targetType.isInstance( element ) ) {
throw new IllegalArgumentException(
"Parameter value [" + element + "] was not matching type [" +

);
}
}
} else {
throw new IllegalArgumentException(

}
}
}
if ( parameterBindings == null ) {

}
parameterBindings.put( parameter, value );
}

Gail Badner commented on HHH-5292:
----------------------------------
Please do the following:
* checkout the trunk version http://anonsvn.jboss.org/repos/hibernate/core/trunk
* update a test in entitymanager/src/test/ to reproduce your issue
* update org.hibernate.ejb.AbstractQueryImpl.java with your fix
* create two patches using "svn diff" (one for your test and one for your
fix), and attach to this issue
Thanks,
Gail

Though I would like to be able to check the individual elements of a primitive array too.
Maybe something like:
{code}
else if ( value.getClass().isArray() ) {
if ( value.getClass().getComponentType().isPrimitive() ) {
for ( int i = 0; i < Array.getLength( value ); i++ ) {
final Object element = Array.get( value, i );
if ( ! parameter.getParameterType().isInstance( element ) ) {
throw new IllegalArgumentException(
"Parameter value [" + element + "] was not matching type ["
+
parameter.getParameterType().getName() + "]"
);
}
}
}
else {
final Object[] array = (Object[]) value;

Actually, for primitive arrays we have the luxury of knowing the elements are all the same
type. That check really could just become:
{code}
else if ( value.getClass().isArray() ) {
if ( value.getClass().getComponentType().isPrimitive() ) {
if ( ! parameter.getParameterType().isAssignableFrom(
value.getClass().getComponentType() ) ) {
throw new IllegalArgumentException(
