Sandor Molnar updated KNOX-3030:
--------------------------------
Description:
In highly concurrent environments Knox may fail to parse the generated
topology from 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
comparing the generated cdp-proxy topology with the existing version:
org.xml.sax.SAXParseException; lineNumber: 35; columnNumber: 20; Error at line
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.Provider and
org.apache.knox.gateway.topology.Param are in unnamed module of loader
java.net.URLClassLoader @668bc3d5)
2024-01-26 10:35:25,173 INFO topology.simple
(SimpleDescriptorHandler.java:generateTopology(622)) - Skipping redeployment of
the cdp-proxy topology because it already exists and has not changed. {noformat}
This will lead to unreachable end-user endpoints.
