Hello We have: – org.ops4j.pax.web.itest.undertow.WhiteboardR6IntegrationTest#testErrorServlet – org.ops4j.pax.web.itest.jetty.WhiteboardR6IntegrationTest#testErrorServlet – org.ops4j.pax.web.itest.tomcat.WhiteboardR6IntegrationTest#testErrorServlet
which tests servlet with "osgi.http.whiteboard.servlet.errorPage = [ "404", "442", "5xx", "java.io.IOException" ]". This test never failed with such exception... Questions: – did you try debugging and checking what's passed in org.ops4j.pax.web.service.spi.model.ServiceModel#addErrorPageModel? (e.g., value of org.ops4j.pax.web.service.spi.model.ContextModel#classLoader) inside ErrorModel? – why do you use scope = prototype? regards Grzegorz Grzybek wt., 3 wrz 2019 o 16:46 Nhut Thai Le
