Re: [infinispan-dev] Unwrapping exceptions

Personally as a user I'd expect to have a CacheException raised if and only if it's not caused by my own code. Imagine my own lambda is explicitly throwing an exception of a type of my choice, it would be nice to receive that error and not a different one.
