---------------------------------------------------------------

Frankly I really think you need to calm down a bit and step back from this 
for a period of time. It is rather evident (certainly to me) you are taking 
technical issues personally when they are not and making things overly 
personal when you shouldn't be. If this rather old issue warrants further 
consideration I am sure it will be properly followed up upon at some point. 
This is most certainly not the appropriate venue for an ego/emotionally 
driven tit-for-tat (if you feel the need to carry out a mostly personal 
interchange it is always fine to email me). Over-the-top personal reactions 
will most likely undermine the possible validity of the technical issue at 
hand.

Unless you have a further technical detail to share frankly I have little 
more to say on this.

>                 Key: EJB_SPEC-121
>                 URL: https://java.net/jira/browse/EJB_SPEC-121
>             Project: ejb-spec
>          Issue Type: Improvement
>    Affects Versions: 3.2
>            Reporter: mkarg
>
> Triggered by a dispute about an unclear section of th EJB 3.2 specification 
> I'd like to suggest that the next maintenance release of the EJB 
> specification provides the following clarification:
>  
> "A persistent timer MUST survive EJB redeployment."
>  
> Optionally I want to suggest that the specification goes further than that 
> an says:
>  
> "A persistent timer MUST survive EJB redeployment and undeployment."
>  
> Justification: Given a long-running business process like subscription 
> management, there are two ways to deal with future business events like 
> automatic subscription extension. The first way is to write the date of 
> next contract extension into a persistent database using JPA, and have a 
> non-persistent timer check this database table daily for any due contracts. 
> This solution survives even undeployment followed by redeployment, as the 
> database content is not touched. The second way is to not write the next 
> contract extension date into the database, but simply set up a persistent 
> timer firing on the day of extension. This offloads the burden of contract 
> book-keeping from the application's code and data tables to the EJB 
> container's persistent timer service. Certainly, an application programmer 
> would expect that when doing a redeployment (or even an undeployment and 
> deployment) will behave exactly the same -- and not kill any timers, as 
> those are not technical instruments but merely valueable business data. If 
> the container would kill that persistent timers at redeployment or 
> undeployment, this business data will get lost, which is clearly not what a 
> developer expects from any persistent technologoy!
>  
> Currently the RI (GlassFish 4.0) by default deletes programatically created 
> persistent timers when a new version of an application is provided by means 
> of redeployment (https://java.net/jira/browse/GLASSFISH-20295). This foils 
> the core idea of both, redeployment (in contrast to undeployment followed 
> by deployment) and persistent timers and threatens the realiability of 
> business applications by behaving in a non-expected way by default.
