NPE on GenericURL class on v1.20

[Paulo Fernandes]

Hi all,

i have a server in production using google-http-java-client 1.20 , and i'm casually getting npe at GenericUrl.java:599, the cause is the fact that "value" is somethimes null..

  private static boolean appendParam(boolean first, StringBuilder buf, String name, Object value) {

    if (first) {

      first = false;

      buf.append('?');

    } else {

      buf.append('&');

    }

    buf.append(name);

------>  String stringValue = CharEscapers.escapeUriQuery(value.toString());

    if (stringValue.length() != 0) {

      buf.append('=').append(stringValue);

    }

    return first;

  }

java.lang.NullPointerException

...

the request is for google translate. in order to  debug this issue i built a lot of diferent tests calling UriTemplate  (the class that will call GenericUrl.java) "expand" method, passing all types of possible parameter combinations, and i never managed to reproduce this error locally..

has anyone ever faced this issue ? maybe even using libraries other than googel translate..

Thanks,

Paulo f
