Update Infinispan objects maintaining expiration time

I'm using an instance of org.infinispan.Cache (Infinispan API) so it's very easy to put, remove, find objects.

The object I put has a fixed lifespan. For example, I put an object with a lifespan of 5 minutes. During the lifetime of this object, I want to modify some attributes but I want to maintain the original lifespan. For example, after 2 minutes I update the object. I want my object to expire is 3 minutos after update.

I think a simple way is getting the object, calculating the remaining lifespan and calling replace() method on the cache API with the remaining lifespan. But this method is a little tricky.

I reviewed org.infinispan.Cache API and I couldn't find a simple way to update/replace the object and maintain the original lifespan. All methods receive lifespan as arguments.

Is there a simple way to update infinispan objects maintaining the original lifespan?

Thank you very much!

The only other option is to modify your objects directly. That will work if your cache is not clustered and you are neither using a cache store nor enabling store-as-binary.

However, it would require your objects to be synchronized, and it destroys transaction isolation. So I would recommend keeping your current approach.
