CLONE -NullPointerException when using BigInteger in a query ------------------------------------------------------------ Key: HHH-908 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-908 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.0.5 Environment: Hibernate 3.0.5, Oracle 9.2.0.6 Reporter: Karl Wettin Assignee: Gavin King Priority: Minor Fix For: 3.1 rc 1 Original Estimate: 0.5h Remaining Estimate: 0.5h When I'm using a BigInteger in a query like Query query = session.createQuery("from Antrag as antrag where antrag.m_kreditId = (:kreditId)"); query.setBigInteger("kreditId", new BigInteger(kreditId)); I get the following Exception: java.lang.ClassCastException at org.hibernate.type.BigDecimalType.set(BigDecimalType.java:28) at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:62) at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:44) at org.hibernate.hql.classic.QueryTranslatorImpl.bindNamedParameters(QueryTranslatorImpl.java:877) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1178) at org.hibernate.loader.Loader.doQuery(Loader.java:390) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:218) at org.hibernate.loader.Loader.doList(Loader.java:1593) at org.hibernate.loader.Loader.list(Loader.java:1577) at org.hibernate.hql.classic.QueryTranslatorImpl.list(QueryTranslatorImpl.java:890) I believe that this bug be caused by a typo in org.hibernate.hql.ast.ArithmeticNode: if ( x==Hibernate.BIG_DECIMAL || y==Hibernate.BIG_DECIMAL ) return Hibernate.BIG_DECIMAL; if ( x==Hibernate.BIG_INTEGER || y==Hibernate.BIG_INTEGER ) return Hibernate.BIG_DECIMAL; should actually be: if ( x==Hibernate.BIG_DECIMAL || y==Hibernate.BIG_DECIMAL ) return Hibernate.BIG_DECIMAL; if ( x==Hibernate.BIG_INTEGER || y==Hibernate.BIG_INTEGER ) return Hibernate.BIG_INTEGER;
