No generate database with Hibernate 5 and Glassfish4

Question

I migrate my application to Hibernate 5 and Glassfish 4. When I deploy, it try generate database but this error appears:

aused by: org.hibernate.tool.schema.spi.SchemaManagementException: Unable to execute schema management to JDBC target [create table banca (id int8 not null, descricao varchar(255), publica boolean not null, primary key (id))]

It's true, because the table 'banca' exists in database, but my persistence.xml is:

   <persistence-unit name="myPU" transaction-type="JTA">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>jdbc/myDS</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
    </properties>
</persistence-unit>

[EDIT] The persistence.xml is being used, in Glassfish log appears:
