> NIFI-10888 introduced a BufferedInputStream inside of the ContentClaimInputStream to speed up rewinding in small flow files (<1MB).
> Under some circumstances it can happen in reset that the delegate stream is closed and a new delegate stream is created, but the bufferedIn is not recreated with the new delegate.
> During the next read this leads to a situation where it tries to read from bufferedIn and bufferedIn in turn tries to read from the old and closed delegate stream causing an IOException or FlowFileAccessException.
