      "Message": "Ok, I've looked at this further and decided that the error is poor.  However, I do think there should be an exception thrown by DotNetZip.  You should not use OpenReader() to read a zip entry from a ZipInputStream.  The ZipInputStream() programming model does not require it, and is actually simpler without OpenReader().  Check the doc for full details.  \r\n\r\nI will change DotNetZip to throw a more descriptive, appropriate exception in the future. \r\n",
