-----------------------------------
Summary: The JavaScript scripting engine can generate classloader
leaks
Key: SLING-4783
URL: https://issues.apache.org/jira/browse/SLING-4783
Project: Sling
Issue Type: Bug
Components: Scripting
Reporter: Radu Cotescu
Assignee: Radu Cotescu
Fix For: Scripting JavaScript 2.0.18
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.
