Hi, Looks like an error w/the classpath, IgniteUtils is in the same mode as the Ignition class therefore this looks like the igntie-core was not loaded correctly. Ignite 2.7 is an old version. I would try to simplify the scenario by loading the latest Ignite version https://ignite.apache.org/download.cgi#binaries and using only ignite-core and ignite-spring. Don't load any other ignite or other modules/libraries. Verify the classpath of the java process running WildFly using jinfo or other java tool.
