EclipseLink - Not creating relationship

Question

I don't know why relationships is not been created in my database. I have 7 relationships in a table wherein 5 relations works fine, but 2(materialServico,unidadeMedida) won't appears in database(looking at CONSTRAINT REFERENCES) and nothing appear on log. Anyone experienced this? I'm using eclipselink 2.5.1 with spring 3.2.1.RELEASE and SqlServer 2012(also tested in postgresql). Normally I use Hibernate as ORM...

@JoinColumns({
    @JoinColumn(name = "COD_EMPRESA", referencedColumnName = "COD_EMPRESA", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_FILIAL", referencedColumnName = "COD_FILIAL", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_CONTA_CONTABIL", referencedColumnName = "COD_CONTA_CONTABIL", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "DATA_CONTA_CONTABIL", referencedColumnName = "DATA_CONTA_CONTABIL", nullable = true, insertable=false, updatable=false)})
@ManyToOne(optional = false)
private Conta conta = new Conta();

@JoinColumns({
    @JoinColumn(name = "COD_EMPRESA", referencedColumnName = "COD_EMPRESA", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_FILIAL", referencedColumnName = "COD_FILIAL", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_UNIDADE_MEDIDA", referencedColumnName = "COD_UNIDADE_MEDIDA", nullable = true, insertable=false, updatable=false)})
@ManyToOne(optional = false)
private UnidadeMedida unidadeMedida = new UnidadeMedida();

 @JoinColumns({
    @JoinColumn(name = "COD_EMPRESA", referencedColumnName = "COD_EMPRESA", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_FILIAL", referencedColumnName = "COD_FILIAL", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_NAT_OPERACAO", referencedColumnName = "COD_NAT_OPERACAO", nullable = true, insertable=false, updatable=false)})
@ManyToOne(optional = false)
private NaturezaOperacao naturezaOperacao = new NaturezaOperacao();

@JoinColumns({
    @JoinColumn(name = "COD_EMPRESA", referencedColumnName = "COD_EMPRESA", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_FILIAL", referencedColumnName = "COD_FILIAL", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "CHAVE_NFE", referencedColumnName = "CHAVE_NFE", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "DATA_REF", referencedColumnName = "DATA_REF", nullable = true, insertable=false, updatable=false)})
@ManyToOne(optional = false)
private MestreNotaFiscal mestreNotaFiscal = new MestreNotaFiscal();

@JoinColumns({
    @JoinColumn(name = "COD_EMPRESA", referencedColumnName = "COD_EMPRESA", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_FILIAL", referencedColumnName = "COD_FILIAL", nullable = true, insertable=false, updatable=false),
    @JoinColumn(name = "COD_ITEM", referencedColumnName = "COD_ITEM", nullable = true, insertable=false, updatable=false)})
@ManyToOne(optional = true)
private MaterialServico materialServico;

Sql logs: It creates the FK for mestreNotaFiscal, filial, conta, naturezaOperacao, empresa. Don't show more FK from this table in the log.

I changed the implementation from eclipselink to hibernate(4.2.1.Final) and it worked! I don't know why have this problem and don't know how to use eclipselink in this situation.
