I’m using KNIME on the command line and getting some error. I believe this is an extension node error, but I do not know how to solve it, I’ll be happy if anyone can help The error is: CompilerOracle: exclude javax/swing/text/GlyphView.getBreakSpot jan 11, 2019 1:19:43 PM org.apache.cxf.bus.osgi.CXFExtensionBundleListener addExtensions INFORMAÇÕES: Adding the extensions from bundle org.apache.cxf.cxf-rt-transports-http (297) [org.apache.cxf.transport.http.HTTPTransportFactory, org.apache.cxf.transport.http.HTTPWSDLExtensionLoader, org.apache.cxf.transport.http.policy.HTTPClientAssertionBuilder, org.apache.cxf.transport.http.policy.HTTPServerAssertionBuilder, org.apache.cxf.transport.http.policy.NoOpPolicyInterceptorProvider] jan 11, 2019 1:19:43 PM org.apache.cxf.bus.osgi.CXFExtensionBundleListener addExtensions INFORMAÇÕES: Adding the extensions from bundle org.apache.cxf.cxf-rt-transports-http-hc (298) [org.apache.cxf.transport.http.HTTPConduitFactory, org.apache.cxf.transport.ConduitInitiator] jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://cxf.apache.org/blueprint/core](http://cxf.apache.org/blueprint/core) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://cxf.apache.org/configuration/beans](http://cxf.apache.org/configuration/beans) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://cxf.apache.org/configuration/parameterized-types](http://cxf.apache.org/configuration/parameterized-types) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://cxf.apache.org/configuration/security](http://cxf.apache.org/configuration/security) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://schemas.xmlsoap.org/wsdl/](http://schemas.xmlsoap.org/wsdl/) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://www.w3.org/2005/08/addressing](http://www.w3.org/2005/08/addressing) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://schemas.xmlsoap.org/ws/2004/08/addressing](http://schemas.xmlsoap.org/ws/2004/08/addressing) jan 11, 2019 1:19:44 PM org.apache.cxf.bus.blueprint.NamespaceHandlerRegisterer register INFORMAÇÕES: Registered blueprint namespace handler for [http://cxf.apache.org/blueprint/jaxrs](http://cxf.apache.org/blueprint/jaxrs) INFO main BatchExecutor ===== Executing workflow /home/user/work/Learning.knwf ===== WARN main Node No row key column selected generate a new one WARN KNIME-Worker-4 Node No aggregation column defined WARN KNIME-Worker-4 Node No aggregation column defined WARN KNIME-Worker-4 Node No grouping column included.
