2024-07-08 15:24:41,666 [ 464381] SEVERE - #c.i.o.u.ObjectTree - Memory leak detected: 'org.jboss.tools.intellij.openshift.tree.application.ApplicationsRootNode@cb88e22' (class org.jboss.tools.intellij.openshift.tree.application.ApplicationsRootNode) was registered in Disposer as a child of 'ROOT_DISPOSABLE' (class com.intellij.openapi.util.Disposer$2) but wasn't disposed.
Register it with a proper parentDisposable or ensure that it's always disposed by direct Disposer.dispose call.
