Suppose we have a class @Entity class SampleWithPrimitiveId { @Id long id; } Trying to lookup the id property through IdentifiableType type = // … type.getId(type.getIdType().getJavaType()) fails with Expected id attribute type [class java.lang.Long] on the existing id attribute [SingularAttributeImpl[BasicTypeImpl@1973147899:long [ javaType: long],org.eclipse.persistence.mappings.DirectToFieldMapping[id-->SAMPLEWITHPRIMITIVEID.ID]]] on the identifiable type [EntityTypeImpl@1313610571:SampleWithPrimitiveId [ javaType: class org.springframework.data.jpa.domain.sample.SampleWithPrimitiveId descriptor: RelationalDescriptor(org.springframework.data.jpa.domain.sample.SampleWithPrimitiveId --> [DatabaseTable(SAMPLEWITHPRIMITIVEID)]), mappings: 1]] but found attribute type [long]. I'll prepare a reproducing branch in Spring Data JPA. I can currently only test that against 2.4.0 as both 2.4.2 and 2.5.0 fail to bootstrap due to https://bugs.eclipse.org/bugs/show_bug.cgi?id=411560.
Steps to reproduce: git clone https://github.com/SpringSource/spring-data-jpa cd spring-data-jpa git checkout eclipselink-415027 mvn clean test The EclipseLink version is held in a property in the pom.xml so it should be easy to test that running against more recent versions as well.

Having the same problem when using MapsId: [CODE] @Entity @Table(name = "etl_servidor_publico", schema = "sapeo") public class EtlServidorPublico implements Serializable { @Id @Column(name = "nomeacao_id") private Long id; @MapsId @OneToOne(optional = false) @JoinColumn(name = "nomeacao_id", nullable = false, updatable = false) private Nomeacao nomeacao; [/CODE] The exception: [CODE] java.lang.IllegalArgumentException: Expected id attribute type [class java.lang.Long] on the existing id attribute [SingularAttributeImpl[EntityTypeImpl@535754249:Nomeacao [ javaType: class br.gov.to.secad.sapeo.model.Nomeacao descriptor: RelationalDescriptor(br.gov.to.secad.sapeo.model.Nomeacao --> [DatabaseTable(sapeo.nomeacao)]), mappings: 12],org.eclipse.persistence.mappings.OneToOneMapping[nomeacao]]] on the identifiable type [EntityTypeImpl@22731072:EtlServidorPublico [ javaType: class br.gov.to.secad.sapeo.model.EtlServidorPublico descriptor: RelationalDescriptor(br.gov.to.secad.sapeo.model.EtlServidorPublico --> [DatabaseTable(sapeo.etl_servidor_publico)]), mappings: 19]] but found attribute type [class br.gov.to.secad.sapeo.model.Nomeacao]. [/CODE] Tested against 2.4.0, 2.4.2 and 2.5.0.
I have the same problem with EclipseLink 2.5.2.
Also in 2.6.0
Same Problem in 2.7.1. Occurred for me when I changed the @Id type of an entity from java.lang.Long to long. There's nothing special about the entity, however, it is part of a @OneToMany/@ManyToOne relation (the entity where it occurs holds the owning @ManyToOne side). Does anyone know why this is happening? Workarounds?
