Akitoshi Yoshida commented on CAMEL-8284:
-----------------------------------------

this is a known limitation of camel's stream caching.
http://mail-archives.apache.org/mod_mbox/camel-users/201302.mbox/%3ccaf8t5xvr8rnhs8z5gzdpppam5hq9j0f4bbsuct5hwpmvao0...@mail.gmail.com%3E

I think we should just make camel's stream cache work similar to cxf's stream 
caching, which can be read multiple times by multiple threads.

>
> If the multi-cast processor gets as an input a stream cache in the parallel 
> processing mode, then the stream is read by different threads concurrently. 
> This leads to wrong results.
> The attached patch solves this issue. The idea of the patch is to provide a 
> copy of the stream cache to each thread. The copy will use the same cache of 
> the original stream cache, only the stream which accesses the cached data  
> will be a separate instance. For this, we introduced the new method
>    copy()
> in the StreamCache class.
