[jira] [Commented] (TAP5-1430) prevent property binding to itself

["Howard M. Lewis Ship (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-1430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13014303#comment-13014303 ] 

Howard M. Lewis Ship commented on TAP5-1430:
--------------------------------------------

At the very least, accomplishing this would require a change to some public APIs, not to mention the fact that the information needed to detect this is somewhat scattered around the place. Maybe a hacked solution is possible inside the worker for the @Parameter annotation.

> It is currently possible to bind a property to itself like so:
> @Property
> @Parameter(value="actionZone")
> private String actionZone;
> This causes a StackOverflowError where it should just assign the default literal value "actionZone" to the property actionZone. Or it should complain and throw an Exception informing the developer that you cannot bind in this way without specifying the prefix literal:
