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

    Attachment: sling-2881.r1551665.patch

proposed patch that implements alex's suggestion.

> Performance of an appplication using Sling i18n JcrResourceBundleProvider suffers drastically if nodes with mixin type mix:language are modified frequently.
> The reason for the performance degradation is that JcrResourceBundleProvider registers a JCR event listener for node types: mix:language and sling:Message. It then clears the i18n resource bundle cache whenever a node with these types appears in an event.
> The JCR 2.0 spec indicates applications should use a mix:language type as the standard way to provide a property specifying the natural language which the content of a  node is expressed.
> Therefore clearing the resource bundle cache on a change to *any* node with a mix:language type is inappropriately broad.
