    The upcoming Android Studio runs in a JVM but has classes from Android and that confused OkHttp!

 *  Fix: Include the header `Accept: text/event-stream` for SSE calls. This header is not added if
    the request already contains an `Accept` header.

 *  Fix: Don't crash with a `NullPointerException` if a server sends a close while we're sending a
    ping. OkHttp had a race condition bug.

## Benutzerdefinierte Header hinzufügen { #add-custom-headers }

Es gibt Situationen, in denen es nützlich ist, dem HTTP-Error benutzerdefinierte Header hinzuzufügen. Zum Beispiel in einigen Sicherheitsszenarien.

Sie werden es wahrscheinlich nicht direkt in Ihrem Code verwenden müssen.

Aber falls Sie es für ein fortgeschrittenes Szenario benötigen, können Sie benutzerdefinierte Header hinzufügen:

isolated classloader

The plugin artifact and its dependency artifacts will be loaded in an isolated ClassRealm which is simply an extension of the standard URLClassLoader. Mercury would be responsible for resolving and retrieving the dependencies which would then be used to populate a ClassRealm where there would be a connection to the host applications ClassRealm as the parent but the search order would be child first, and the parent ClassRealm can optionally choose to limit the searching...
