    XMLWordPrintable

Details

    Description

      If ParamConverterProviders are registered, and null arguments are passed to a REST API call, a NullPointerException is thrown in org.jboss.resteasy.client.microprofile.ProxyInvocationHandler.invoke().

      https://github.com/resteasy/Resteasy/blob/master/resteasy-client-microprofile/src/main/java/org/jboss/resteasy/microprofile/client/ProxyInvocationHandler.java

      for (Object arg : args) {
          if (parameterAnnotations[index].length > 0) {
              ParamConverter<?> converter = ((ParamConverterProvider) p)
                  .getConverter(arg.getClass() /** <-- NPE when arg is null **/, 
                  null, parameterAnnotations[index]);
