Re-opening this one, test the is currently failing in develop - I've disabled it with https://github.com/OpenNMS/opennms/commit/b84cafe6ce956b092d58af7371ecdf2e06b64a83.

We also need to backport this to foundation-2018 if applicable.

It looks like the problem is caused by multiple definitions of the class org.json.JSONArray.
org.json.JSONArray is defined in the following jars:

Same problem for me. Changing the icon worked in Version 21.0.4. Version 22.0.3 produces the same error for me. The important part in the log is imho:

Caused by: java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "org.opennms.features.topology.app.internal.ui.icons.IconSelectionComponent$$Lambda$663/1566691508.call(Lorg/json/JSONArray;)V" the class loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoader) of the current class, org/opennms/features/topology/app/internal/ui/icons/IconSelectionComponent$$Lambda$663, and the class loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoader) for interface com/vaadin/ui/JavaScriptFunction have different Class objects for the type org/json/JSONArray used in the signature
