>
> The implementation of the JavaScript scripting engine, based on Rhino, can
> lead to classloader leaks due to Rhino's {{ClassCache}} if the used
> classloader for loading objects is a {{DynamicClassLoader}}. The cache is
> used by default to cache object translation from JavaScript to Java and
> generally outlives the objects it stores, holding a hard reference to them.
> Disabling the cache is not a solution as synthetic tests proved that the
> execution of JavaScript code had increased two times.
