-----------------------------------------

No exceptions are thrown in the process, it hangs forever and have to be exited manually. Please guide me if its possible to collect more information somehow.

>          Issue Type: Question
>          Components: jpa
>    Affects Versions: 2.4.2

>
> We are using OpenJPA to manage a relational database for an offline desktop application.
> OpenJPA does not works on Linux OS on which /etc/hosts file is having incorrect configuration.
>  
> We have observed that, it works if the file is not present or empty.
>  
> The application we have developed does not require any internet connection hence we want OpenJPA to work even if the host name resolution is not done.
>  
> The OpenJPA API does not provides any such option to override default configuration for hostname resolution or an option to indicate that the database being used is an offline database.
>  
> Please suggest any resolution for this issue.
