> Key: SLING-10615
> URL: https://issues.apache.org/jira/browse/SLING-10615
> Project: Sling
> Issue Type: Bug
> Reporter: Eric Norman
> Assignee: Eric Norman
> Priority: Major
> Fix For: Servlets Resolver 2.8.0

> Time Spent: 0.5h
> Remaining Estimate: 0h

> 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.
