NPE when passing null arguments and ParamConverterProviders are registered

    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]);

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
