Dirk Rudolph updated SLING-7508:
--------------------------------
Description:
Adapting a {{SlingHttpServletRequest}} to a servlet that is registered using
sling.servlet.paths to a {{@Model}} fails in the following StackOverflowError:
{code}
java.lang.StackOverflowError: null
...

org.apache.sling.models.impl.AdapterImplementations.getModelClassForResource(AdapterImplementations.java:318)

org.apache.sling.models.impl.AdapterImplementations.getModelClassForResource(AdapterImplementations.java:322)
{code}
See for example the following pseudo code:
{code}
@SlingServlet(paths = "/apps/mypath")
class MyServlet extends SlingSafeMethodsServlet {
doGet(request) { request.adaptTo(Model.class); }
}
interface Model {
...
}
@Model(adaptables = SlingHttpServletRequest.class, adapters = {ModelImpl.class,
Model.class})
class ModelImpl implements Model {
...
}
{code}
