SlingScriptHelper#getServices() causes ClassCastException
---------------------------------------------------------
Key: SLING-2341
URL: https://issues.apache.org/jira/browse/SLING-2341
Project: Sling
Issue Type: Bug
Components: Scripting
Affects Versions: Scripting Core 2.0.18
Reporter: Julian Sedding
Fix For: Scripting Core 2.0.20
Attachments: SLING-2341.patch
The implementation of ScriptHelper#getServices() creates an Object[] and tries
to cast it to the generics class. This results in a ClassCastException, as an
Object[] cannot be cast to a more specific array (i.e. ServiceType[]). The
solution is to create an array of the correct type and size using
java.util.reflect.Array#newInstance(), see discussion on stackoverflow[0].
