Hi,
on a production system running an old Geoserver I’m seeing the following stack trace:
Caused by: java.lang.NullPointerException
at org.eclipse.emf.ecore.util.EcoreEList.resolveProxy(EcoreEList.java:212)
at org.eclipse.emf.ecore.util.EcoreEList.indexOf(EcoreEList.java:411)

at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:882)
No way to reproduce it locally… looking at the code is seems that it could happen if the item to be removed
is not found in the list, then the code checks if the list contains proxies by trying to unwrap them, and either
it turns out the list contains a null value, or the value is not null, it’s a proxy, and the list has no owner…
The above means nothing to me however… does that ring a bell to anyone? Anything you might have
already seen? It’s happening while making WFS 2.0 requests to a 2.4.x GeoServer, does not happen
with 1.1 and 1.0.
Checked the ticket tracker, could not find anything related…
Cheers
Andrea
