[infinispan-dev] Management of shared caches

Had a look at DefaultCacheManager today and I see it has no mechanism for controlling the stopping of shared caches. Multiple independent callers to getCache("foo") can get a ref to the foo cache, and then any of them can call stop() on it. A few possibilities come to mind: 1) Add a releaseCache method, do some reference counting, and stop the cache when all refs are released. Remove the cache from the "caches" map. 2) And/or, wrap the cache in a wrapper whose stop() method doesn't call through to the wrapped cache until stop() is called on all wrappers 3) Advise in the javadoc that shared caches are supported, but if they are used it's the users responsibility to ensure that at least one but only one caller calls stop() on the cache. At least for the AS use cases, this should be OK, since an Infinispan Cache will be analogous to a JBC Region, and there's only one user for a given region. -- Brian Stansberry Lead, AS Clustering JBoss by Red Hat
