A validation message should be provided when duplicate column pairs are defined for join columns/inverse join columns/pk join columns. This validation applies when the source and reference column of the defined pairs are both duplicated. Take join table definition for instance, the duplicate should be reported when a join table is defined like 

@ManyToMany
@JoinTable(name = "PROJ_EMP", schema = "APP2",
           joinColumns = { @JoinColumn(name = "EMP_ID",        
                                       referencedColumnName = "EMP_ID"),
                           @JoinColumn(name = "EMP_ID",
                                       referencedColumnName = "EMP_ID")},
           inverseJoinColumns = { @JoinColumn(name = "PROJ_ID",
                                              referencedColumnName = "PROJ_ID"),
                                  @JoinColumn(name = "PROJ_ID",
                                              referencedColumnName = "PROJ_ID")
})
    public List<Project> projects; 


Reproducible: Always

Steps to Reproduce:
Define join columns/inverse join columns/pk join columns for relationship mappings
