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.

          Bug - A problem which impairs or prevents the functions of the product. RESTEASY-2974 ClientConfiguration.toString(null, type, annotations) causes NPE

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
