      Description

      Having m2release plugin installed on Hudson 2.2.0, it generates the following error when we try to perform a release (testing with dryRun)

      Apr 16, 2012 2:31:16 PM org.apache.catalina.core.StandardWrapperValve invoke
      SEVERE: Servlet.service() for servlet Stapler threw exception
      java.lang.ClassCastException: net.sf.json.JSONNull cannot be cast to net.sf.json.JSONObject
      at org.jvnet.hudson.plugins.m2release.M2ReleaseAction.doSubmit(M2ReleaseAction.java:239)
      at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

      ...

      Examining the source code, for M2ReleaseAction, it happens because there are not values in the form data for the parameter named "parameter"

      M2ReleaseAction Code:
      public void doSubmit(StaplerRequest req, StaplerResponse resp) ... {
      ...
      JSONArray a = JSONArray.fromObject(formData.get("parameter"));
      for (Object o : a) {
      JSONObject jo = (JSONObject) o;
      ...

      In order to solve this, check that we have "parameter"; or check for a possible JSONNull object:

      Possible Fix:
      JSONArray a = JSONArray.fromObject(formData.get("parameter"));
      for (Object o : a) {
      if (o instanceof JSONObject)

      { JSONObject jo = (JSONObject) o; ... }

      ...

      Note: The plugin is installed on Hudson with the workaround described in #JENKINS-12991
