-----------------------------------
Summary: DefaultErrorHandlerServlet json error response may throw
a ClassCastException
Key: SLING-10615
URL: https://issues.apache.org/jira/browse/SLING-10615
Project: Sling
Issue Type: Bug
Reporter: Eric Norman
Assignee: Eric Norman
Fix For: Servlets Resolver 2.8.0
The DefaultErrorHandlerServlet json error response will fail with a
ClassCastException if the "javax.servlet.error.exception_type" request
attribute is not a String object.
There is some inconsistency in what type of object the
"javax.servlet.error.exception_type" should be in the error handler.
* The servlet 3.1 specifications states that this attribute should be a
"java.lang.Class" object.
* The SlingConstants#ERROR_EXCEPTION_TYPE javadoc states that this attribute
should be a "java.lang.String" object.
In the interest of backward compatibility, the DefaultErrorHandlerServlet
should try to handle it if the attribute value is either a String or a Class
object.
