             Summary: Add ability to cancel an event in a listener
                 Key: ISPN-6443
                 URL: https://issues.jboss.org/browse/ISPN-6443
             Project: Infinispan
          Issue Type: Enhancement
          Components: Core, Expiration
    Affects Versions: 8.2.0.Final
            Reporter: Vincent Massol


My use case is the following:
* I have some lenghty computation that I cache
* I don't want users to incur the wait before the computation is finished
* Thus, upon expiration, I'd like to put back the entry in the cache and start a thread to perform a recomputation (which would put the recomputed value in the cache)
* The issue is that the cache has a lock on the entry and thus I can't put it back in the cache.

Thus one solution is to be able to cancel the expiration event (and thus not have to put back the entry in the cache).
