-----------------------------------
Summary: SAXException occurs while parsing old topology on the
descriptor handle path
Key: KNOX-3030

Project: Apache Knox
Issue Type: Bug
Components: Server
Reporter: Sandor Molnar
Assignee: Sandor Molnar
Fix For: 2.1.0
In highly concurrent environments Knox may fail to parse descriptors/shared
providers thus topology deployment fails with the following error:
{noformat}
2024-01-26 10:35:25,173 ERROR topology.simple
(SimpleDescriptorHandler.java:shouldPersistGeneratedTopology(682)) - Error

35 char 20: class org.apache.knox.gateway.topology.Provider cannot be cast to
class org.apache.knox.gateway.topology.Param

org.apache.knox.gateway.topology.Param are in unnamed module of loader

This will lead to unreachable end-user endpoints.
