[jboss-user] [JBossCache] - problems with jalapeno/cayenne JBC optimistic cache with inv

[nielsenk]

After debugging and reading through the code, it seemed to me that jalapeno/cayenne JBC will always send an eviction on any put to the cache.  The problem I am facing goes as follows:  

I am using hibernate for persistence in a clustered environment.  hibernate is running in side of a servlet container (SunONE to be specific).  I planned on using JBC optimistically with asynchronous invalidations but when I run under this configuration I get the following problem:

A loads X.v1 from the database.
A sends invalidation(eviction) on put to local JBC (since B is empty no worries).
A has warm cache

B loads X.v1 from the database. 
B sends invalidation(eviction) on put to local JBC.  
B has warm cache

A evicts X.v1 from cache and now has a cold cache even though the data has not changed.

Is this a known issue/feature?  I cant imagine we are the only organization that wishes to run under this configuration.

Looking at the code it seems that the InvalidationInterceptor only operates in this way (sending evictions).  

I can send configs and such if need be.  

Thanks in advance,
Keith.
