cached exceptions may have confusing stack traces

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enable an exceptionCacheName="..." in a @Cacheable

2. Have said @Cacheable throw an exception (in some unique call stack)

3. Call the same method again with the same parameters (but from a different 
call stack) 

The exception thrown will contain the stack trace of the invocation that first 
cached it. It might be wildly different in other invocations. 

The only "solution" I can think of is to serialize/deserialize the cached 
exception (to produce a clone of sorts) and then "fix" the stack trace on the 
clone before throwing it. That operation would come at an expense so this 
should perhaps be optional behavior.
