Coyote
fix 54690: Fix a regression caused by the previous fix for 54406. If no values are specified for sslEnabledProtocols or ciphers use the default values for server sockets rather than the default values for client sockets. (markt)
Web applications
update Correct Deployer, Manager and Context pages of Tomcat documentation. (kkolinko)
jdbc-pool
fix 52318: Version for imported package org.apache.juli.logging is extended to include also 7.0.x versions. The fix is applicable only when running in OSGi environment. Patch provided by Martin Lichtin. (violetagg)
fix 54599: Do not print connection password in PoolProperties.toString(). Based on a patch by Daniel Mikusa. (kkolinko)

Other
fix Update to Apache Commons Daemon 1.0.14 to resolve 54609 which meant that installation of Windows service could fail producing incorrect service launch command. (mturk)
fix Ensure HEAD requests return the correct content length when the requested resource uses a Writer. Patch by Nick Williams. (markt)
Tomcat 7.0.38 (markt)not released
Catalina
fix Ensure that the request start time (used by the access log valve to calculate request processing time) is correctly recorded for the HTTP NIO connector. In some cases the request processing time may have been longer than that recorded. (markt)
update Add one more library from JDK 7 to the value of jarsToSkip property in the catalina.properties file. (kkolinko)
add 53871: If annotation scanning results in a StackOverflowError due to broken class dependencies, add the class hierarchy that triggered the exception to the error message. (markt)

update Provide more consolidated servlet MBean data in the webapp MBean. (rjung)
fix 54584: Take account of the delegate attribute when building the web application class path to pass to the JSP compiler. (markt)
fix Copy the updated and re-packaged UTF-8 decoder from Tomcat 8.0.x and use this improved decoder for WebSocket connections. Remove the WebSocket specific UTF-8 decoder. (markt)
fix 54602: Recycle the byte to character converter used for URIs between requests to ensure an error in one request does not trigger a failure in the next request. (markt)
fix 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)
fix 54624: Ensure that the correct request body length is used when swallowing a request body after FORM authentication prior to restoring the original request preventing possible hanging when restoring POST requests submitted over AJP. (markt)
fix 54628: When writing binary WebSocket messages write from start position in array rather than the start of the array. Patch provided by blee. (markt)

Coyote
fix 54456: Ensure that if a client aborts a request when sending a chunked request body that this is communicated correctly to the client reading the request body. (markt)
update Update the native component of the APR/native connector to 1.1.27 and make that version the recommended minimum version. (markt)

fix 54483: Correct one of the Spanish translations. Based on a suggestion from adinamita. (markt)
fix Prevent the SSO deregister when web application is stopped or reloaded. When StandardManager(pathname="") or DeltaManager stops normally, all sessions in the context are expired. In this case, because most sessions is not time-out, SSO deregister was triggered. (kfujino)
fix Include the exception in the log message if the parsing of the context.xml file fails. (markt/kkolinko)
fix 54497: Make memory leak detection code more robust so a failure in the leak detection code does not prevent the Context from stopping unless the error is fatal to the JVM. (markt)
fix 54507: Do not start the background thread that is used for expiring sessions (amongst other things) until the web application is fully started. Stop the background thread as soon as the web application is stopped. (markt)

fix 54324: Allow APR connector to disable TLS compression if OpenSSL supports it. (schultz)
fix 54406: Fix NIO HTTPS connector to prune specified ciphers and sslEnableProtocols options to those supported by the SSL implementation, sharing logic with the BIO connector. Modified ciphers and sslEnabledProtocols option pruning to not silently revert to JVM defaults when none of the options specified are supported - new behaviour is to warn and explicitly enable no options. (timw)
fix Align NIO HTTP connector with other HTTP connectors and include leading blank lines when determining the size of the HTTP headers. (markt)
Jasper
fix 53869: Performance improvement for pages with lots of heavily nested tags. Retain a reference to the root JSP context rather than traversing the hierarchy on every call. Based on a patch suggested by Sheldon Shao. (markt)
fix 54440: Correct a regression caused by the changes for 54240 that broke compilation of JSPs with JspC. Patch provided by Sheldon Shao. (markt)
fix 54466: Improve error message by including the name of the file when the java file generated from a tag file cannot be compiled. Based on a patch by Sheldon Shao. (markt)

Coyote
fix 54248: Ensure that byte order marks are swallowed when using a Reader to read a request body with a BOM for those encodings that require byte order marks. (markt)
fix Fix release of processors in AjpNioProtocol. Wrong object was used as a key in the connections map. (kkolinko)
Jasper
add 54240: Add support for auto-detection and configuration of JARs on the classpath that provide tag plug-in implementations. Based on a patch by Sheldon Shao. (markt)
fix 54241: Revert the fix for 35410 as it was not compliant with the JSP specification, specifically that <%= obj %> must be translated to out.print(obj) which in turn becomes out.write(String.valueOf(obj)). This will trigger a NullPointerException if obj.toString() returns null. The fix for 35410 incorrectly suppressed the NullPointerException in this case. (markt)

fix 54044: Correct bug in timestamp cache used by logging (including the access log valve) that meant entries could be made with an earlier timestamp than the true timestamp. (markt)
fix 54054: Do not share shell environment variables between multiple instances of the CGI servlet. (markt)
fix 54060: Use a simple parser rather than a regular expression to parse HTTP Digest authentication headers so the header is correctly parsed. The new approach is also faster and generates less garbage. (markt)

update The HTTP header parser added to address 52811 has been removed and replaced with the light-weight HTTP header parser created to address 54060. The new parser includes a work-around for a bug in the Adobe Acrobat Reader 9.x plug-in for Microsoft Internet Explorer that was identified when the old parser was introduced (53814).
fix 54076: Add an alternative work-around for clients that use SPNEGO authentication and expect the authenticated user to be cached per connection (Tomcat only does this if an HTTP session is available). (markt)
fix 54087: Correctly handle (ignore) invalid If-Modified-Since header rather than throwing an exception. (markt)
fix 54096: In web.xml, <env-entry> should accept any type that has a constructor that takes a single String or char. (markt)
