---------------------------------------------
Yes but please share a thread dump (jstack or kill -3) when it hangs
> Incorrectly configured /etc/hosts file on Linux system causes OpenJPA
> createEntityManager() to hang.

> Key: OPENJPA-2740
> URL: https://issues.apache.org/jira/browse/OPENJPA-2740
> Project: OpenJPA
> Issue Type: Question
> Components: jpa
> Affects Versions: 2.4.2
> Environment: Linux RHEL 7.4
> Reporter: Saurabh Malode
> Priority: Major
>
> 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.
