[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-5817) Passing char[] or byte[] to equal function of CriteriaBuilder throws java.lang.ClassCastException.

Passing char[] or byte[] to equal function of CriteriaBuilder throws java.lang.ClassCastException. -------------------------------------------------------------------------------------------------- Key: HHH-5817 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5817 Project: Hibernate Core Issue Type: Bug Components: entity-manager Affects Versions: 3.6.0 Environment: Hibernate 3.6.0-Finale, derby db, mysql db, hsqldb Reporter: Vyacheslav Dimitrov Priority: Minor Fix For: 3.6.1, 4.0.0.Alpha1 Attachments: hibernate_3_6_0.patch We have byte[] field in one of our entity and we want to make query like this. {code} byte[] var = ...; Predicate p = builder.equal(root.get("ourByteField"), var); criteria.where(p); {code} But this code throws exception: [java] Exception in thread "main" java.lang.ClassCastException: [B cannot be cast to [Ljava.lang.Object; [java] at org.hibernate.ejb.AbstractQueryImpl.registerParameterBinding(AbstractQueryImpl.java:349) [java] at org.hibernate.ejb.QueryImpl.setParameter(QueryImpl.java:364) [java] at org.hibernate.ejb.criteria.CriteriaQueryCompiler$1$1.bind(CriteriaQueryCompiler.java:194) [java] at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:247) [java] at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:441) [java] at ru.petrsu.nest.oqlite.test.TestParser.main(TestParser.java:92) [java] Java Result: 1 because class AbstractQueryImpl has code: {code} ... else if ( value.getClass().isArray() ) { final Object[] array = (Object[]) value; ... {code} We offer to change this "if" like this {code} ... else if ( value.getClass().isArray() && value.getClass().equals(Object[].class)) { final Object[] array = (Object[]) value; ... {code} Due to this new condition we get what we want and our criteria works fine. (At least ClassCastExceptio isn't occured). Patch is attached (Also I can do pull request, if needed).
