a plugin (2). This keeps the underlying object "dumb", so it can be reused in multiple contexts and doesn't contain any special information about how conventions are calculated or what they could be.  In the wild, we've seen some objects set conventions in the object's constructor (3), but this can lead to unexpected assumptions or coupling between plugins.

For external plugins, it's difficult for an object to be used outside the application of a plugin, so following best practices is...

 * They don't specify whether a specific proxy server should be used or how to authenticate with that proxy server.

 * lock-free concurrent reads. Each evaluate() call creates a new Script instance

 * <p>Note on class-level isolation: Compiled Script classes are cached and reused.
 * Class-level state (static fields, metaclass mutations) persists across evaluations
 * of the same script. In Fess, scripts are short expressions configured by

Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.
