-------------------------------------------

{quote}Hmm, I guess you can't use the default creational context. You can probably just wrap CreationalContext and add some additional field to it, and then cast it. If this breaks Weld, it's a bug in Weld, and we can look at other options{quote}

What do you mean exactly? How can I do this after I create CreationalContext instance using BeanManager's createCreationalContext method? Do you mean to wrap that instance with a new instance of a class I write (which implements CreationalContext and has extra cache field) and that instance I cast then in create callback of ContextualLifecycle of the bean?

> Thanks to ISPN-1636, it is now possible to inject the cache into Mapper/Reducer/Callable objects however the cache injected is the default cache not the cache for which the MapReduceTask/DistributedExecutorService has been created which is quite error prone since we don't expect to get the default cache but the current cache.
