Hmm, looks like the stream being read from the FCL either does not contain region information or the region information it does contain does not exist. Where in the lifecycle do you create your regions and register class loaders? Preloading happens in the start() phase of the cache. I wonder if I am losing any registered region info between create() and start(). :-/ On 5 Jun 2008, at 02:11, Brian Stansberry wrote: > Not sure if this is a bug or not or just misconfiguration that the > JBCACHE-1358 fix exposed. > > The cache used for JBAS FIELD granularity web sessions uses region > based marshalling and has a CacheLoader with <preload>/</preload>. > Starting the cache with anything in the persistent store results in > failure.

And this is not necessarily overly complex to do either: When preloading stuff from cache loader: 1) Loop through all Fqns to be preloaded. 2) For each Fqn being preloaded, if any state is regionalised (i.e., a non-null region) check if the region is activated. If so, proceed as normal, if not skip. When a region is actvated: 1) Check if the region is a sub-region of any "preload" Fqns specified in your cache loader cfg. 2) If so, attempt to preload that Fqn, but only for regions that match the one being activated. Skip others. I wonder if it is worth fixing JBCACHE-1009 in 2.2.0. It would warrant another CR in 2.2.0 though. Thoughts? Votes on this?

> TBH, I don't see why I want <preload>/</preload> at all for this usage. Yes - isn't lazy loading a virtue here anyway? :-)

And re: 2.1.1.GA, since JBCACHE-1358 is an obvious bug in JBC, I may port this fix to 2.1.X which will cause future 2.1.X releases to break in the same way. Cheers Manik -- Manik Surtani Lead, JBoss Cache manik(a)jboss.org

Per your comment on lazy loading being a virtue, I don't think I need this for AS 5. It's a nice idea though. Re: another CR, probably should have one anyone so I can put it in the AS hudson runs for a couple days before it goes GA. I can't put in a snapshot anymore -- illegal.
