Hi I am in process of upgrading from tomcat 7.0.33 to 7.0.52 but I am facing IOException: Stream closed in one of the layout jsp. Underlying exception is jasper exception - *org.apache.jasper.JasperException: java.lang.IllegalStateException: Response has already been committed*. Same code is working in 7.0.33 so I doubt that it is happening due to some changes in tomcat so I found out the version from this issue starts. Everything works perfect till v7.0.37 and problem starts with v7.0.39. I started looking the change log for these versions and I can see is "Use the newly added improved UTF-8 decoder for decoding UTF-8 encoded URIs and UTF-8 encoded request bodies. Invalid UTF-8 URIs will not cause an error but will make use of the replacement character when an error is detected. This will allow web applications to handle the URI which will most likely result in a 404 response. The fall-back to decoding with ISO-8859-1 if UTF-8 decoding fails has been removed. *Invalid UTF-8 sequences in a request body will trigger an IOException.* The way the decoder is used has also been improved. The notable change is that invalid sequences at the end of the input now trigger an error rather than being silently swallowed. (markt) "
so want to confirm whether this can be the root cause ? if not what would be the issue - as it works till version 7.0.37 and do not work after version 7.0.39 ? and how to fix this in the code ? -- ~ Prashant Kadam
