NullPointerException on JavaDocParserVisitor for classes without javadoc #178

Closed rmpestano closed 5 years ago

rmpestano commented 5 years ago

When a resource doesn't have javadoc comment at class level but has any field with javadoc then JavadocParser visit method will raise a Nullpointer because classComments.get(className) returns null. Following is an example:

@Stateless
@Path("resourcesPath")
public class JaxRSResources {

  /**
   * a simple javadoc comment
   */
  @Inject
  ApplicationProperties applicationProperties;

The stacktrace is below:
