Bartosz Popiela updated CAMEL-20965:
------------------------------------
Description: InputStreamCache is reset after each step
(org.apache.camel.impl.engine.CamelInternalProcessor.StreamCachingAdvice#after),
and if there are two threads processing the same InputStreamCache (e.g. Seda),
there may be a case where one thread invokes InputStreamCache#reset
(org.apache.camel.support.MessageHelper#resetStreamCache) while another thread
converts this InputStreamCache to String
(org.apache.camel.util.IOHelper#toString(java.io.BufferedReader, long). It
leads to java.io.ByteArrayInputStream#pos being reset and the target String
having duplicate entries. (was: InputStreamCache is reset after each step
