Subject [jira] [Created] (HTTPCLIENT-1157) MemcachedHttpCacheStorage should throw IOExceptions instead of Runtime Exceptions

MemcachedHttpCacheStorage should throw IOExceptions instead of Runtime Exceptions

                 Key: HTTPCLIENT-1157
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1157
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: Cache
    Affects Versions: 4.2 Alpha1
            Reporter: James Miller

The MemcachedHttpCacheStorage class implements HttpCacheStorage which defines that methods
will throw IOExceptions, but the underlying net.spy.memcached.MemcachedClientIF throws runtime
exceptions. These exceptions are not caught in the code where IOExceptions are expected causing
these exception bubble up to the calling code. It seems like the MemcachedHttpCacheStorage
class should treat at least some of these runtime exceptions as IOExceptions so that normal
code execution paths can be followed.  

I'm proposing that MemcachedHttpCacheStorage treat a OperationTimeoutException from the memcached
client as an IOException. This would allow the existing CachingHttpClient code to catch and
log the exception as a warning, instead of bubbling the exception up the calling code.
