+ * ATTENTION: this tests showcases an erroneous condition of an endless circular mapping in the /etc/map. When
+ * this test passes this condition is present. After a fix this test must be adjusted.
+ *
+ * This confirms an issue with the Etc Mapping where a mapping from a node to a child node (here / to /content)
+ * ends up in a endless circular mapping.
+ * The only way to recover from this is to go to the OSGi console and change the /etc/map path in the Resource
+ * Resolver factory.
+ * Either the Etc Mapping discovers this condition and stops it or at least ignores mapping for Composum to allow
+ * the /etc/map to be edited.
