Changelog

Tomcat 8.5.31 (markt)

Catalina

  • Fix: 62263: Avoid a NullPointerException when the RemoteIpValve processes a request for which no Context can be found. (markt)
  • Fix: Fix a rare edge case that is unlikely to occur in real usage. This edge case meant that writing long streams of UTF-8 characters to the HTTP response that consisted almost entirely of surrogate pairs could result in one surrogate pair being dropped. (markt)
  • Fix: Register MBean when DataSource Resource type="javax.sql.XADataSource". Patch provided by Masafumi Miura. (csutherl)
  • Add: Update the internal fork of Apache Commons BCEL to r1829827 to add early access Java 11 support to the annotation scanning code. (markt)
  • Fix: 62297: Enable the CrawlerSessionManagerValve to correctly handle bots that crawl multiple hosts and/or web applications when the Valve is configured on a Host or an Engine. (fschumacher)
  • Fix: 62309: Fix a SecurityException when using JASPIC under a SecurityManager when authentication is not mandatory. (markt)
  • Fix: 62329: Correctly list resources in JAR files when directories do not have dedicated entries. Patch provided by Meelis Müür. (markt)
  • Add: Collapse multiple leading / characters to a single / in the return value of HttpServletRequest#getContextPath() to avoid issues if the value is used with HttpServletResponse#sendRedirect(). This behaviour is enabled by default and configurable via the new Context attribute allowMultipleLeadingForwardSlashInPath. (markt)
  • Fix: Improve handing of overflow in the UTF-8 decoder with supplementary characters. (markt)

Coyote

  • Fix: Correct off-by-one error in thread pool that allowed thread pools to increase in size to one more than the configured limit. Patch provided by usc. (markt)
  • Fix: Prevent unexpected TLS handshake failures caused by errors during a previous handshake that were not correctly cleaned-up when using the NIO or NIO2 connector with the OpenSSLImplementation. (markt)
  • Add: Enable strict validation of the provided host name and port for all connectors. Requests with invalid host names and/or ports will be rejected with a 400 response. (markt)
  • Add: 62273: Implement configuration options to work-around specification non-compliant user agents (including all the major browsers) that do not correctly %nn encode URI paths and query strings as required by RFC 7230 and RFC 3986. (markt)

Jasper

  • Fix: Enable ECJ version 4.7 and later to be used as a drop in replacement for the ECJ version that ships with Apache Tomcat. (markt)
  • Fix: Enable Java 10 to be specified as a JSP source and/or target if a newer ECJ version is used. (markt)

2018-04-07 Tomcat 8.5.30 (markt)

Catalina

  • Fix: 51195: Avoid a false positive report of a web application memory leak by clearing ObjectStreamClass$Caches of classes loaded by the web application when the web application is stopped. (markt)
  • Fix: 52688: Add support for the maxDays attribute to the AccessLogValve and ExtendedAccessLogValve. This allows the maximum number of days for which rotated access logs should be retained before deletion to be defined. (markt)
  • Fix: Ensure the MBean names for the SSLHostConfig and SSLHostConfigCertificate are correctly formed when the Connector is bound to a specific IP address. (markt)
  • Fix: 62168: When using the PersistentManager honor a value of -1 for minIdleSwap and do not swap out sessions to keep the number of active sessions under maxActive. Patch provided by Holger Sunke. (markt)

  • Fix: The OpenSSL engine SSL session will now ignore invalid accesses. (remm)
  • Fix: 62177: Correct two protocol errors with HTTP/2 PUSH_PROMISE frames. Firstly, the HTTP/2 protocol only permits pushes to be sent on peer initiated requests. Secondly, pushes must be sent in order of increasing stream ID. These restriction were not being enforced leading to protocol errors at the client. (markt)

Other

  • Fix: Improve the fix for 61439 and exclude the JPA, JAX-WS and EJB annotations completely from the Tomcat distributions. (markt)
  • Fix: Improve handling of endorsed directories. The endorsed directory mechanism will only be used if the JAVA_ENDORSED_DIRS system property is explicitly set or if $CATALINA_HOME/endorsed exists. When running on Java 9, any such attempted use of the endorsed directory mechanism will trigger an error and Tomcat will fail to start. (rjung)
  • Code: Refactoring in preparation for Java 9. Refactor to avoid using some methods that will be deprecated in Java 9 onwards. (markt)

  • Fix: Implement the requirements of RFC 7230 that any HTTP/1.1 request that specifies a host in the request line, must specify the same host in the Host header and that any such request that does not, must be rejected with a 400 response. This check is optional but disabled by default. It may be enabled with the allowHostHeaderMismatch attribute of the Connector. (markt)
  • Fix: Implement the requirements of RFC 7230 that any HTTP/1.1 request that contains multiple Host headers is rejected with a 400 response. (markt)

Coyote

2017-09-19 Tomcat 8.5.21 (markt)

Catalina

Coyote

  • Update: The minimum required Tomcat Native version has been increased to 1.2.14. This version includes a new API needed for correct client certificate support when using a Java connector with OpenSSL TLS implementation and support for the SSL_CONF OpenSSL API. (rjung)
  • Add: Add support for the OpenSSL SSL_CONF API when using TLS with OpenSSL implementation. It can be used by adding OpenSSLConf elements underneath SSLHostConfig. The new element contains a list of OpenSSLConfCmd elements, each with the attributes name and value. (rjung)
  • Fix: When using a Java connector in combination with the OpenSSL TLS implementation, do not configure each SSL connection object via the OpenSSLEngine. For OpenSSL the SSL object inherits its settings from the SSL_CTX which we have already configured. (rjung)
  • Fix: When using JSSE TLS configuration with the OpenSSL implementation and client certificates: include client CA subjects in the TLS handshake so that the client can choose an appropriate client certificate to present. (rjung)
  • Fix: If an invalid option is specified for the certificateVerification attribute of an SSLHostConfig element, treat it as required which is the most secure / restrictive option in addition to reporting the configuration error. (markt)
  • Fix: Improve the handling of client disconnections during the TLS renegotiation handshake. (markt)
  • Fix: Prevent exceptions being thrown during normal shutdown of NIO connections. This enables TLS connections to close cleanly. (markt)

  • Fix: Improve the warning message when JSSE and OpenSSL configuration styles are mixed on the same SSLHostConfig. (markt)
  • Fix: 61415: Fix TLS renegotiation with OpenSSL based connections and session caching. (markt)
  • Fix: Delay checking that the configured attributes for an SSLHostConfig instance are consistent with the configured SSL implementation until Connector start to avoid incorrect warnings when the SSL implementation changes during initialisation. (markt)
  • Fix: 61450: Fix default key alias algorithm. (remm)
  • Fix: 61451: Correct a regression in the fix to enable the use of Java key stores that contained multiple keys that did not all have the same password. The regression broke support for any key store that did not store keys in PKCS #8 format such as hardware key stores and Windows key stores. (markt)

WebSocket

  • Fix: 60523: Reduce the number of packets used to send WebSocket messages by not flushing between the header and the payload when the two are written together. (markt)
  • Fix: 61491: When using the permessage-deflate extension, correctly handle the sending of empty messages after non-empty messages to avoid the IllegalArgumentException. (markt)

Web applications

  • Fix: Always quote the hostName of an SSLHostConfig element when using it as part of the JMX object name to avoid errors that prevent the associated TLS connector from starting if a wild card hostName is configured (because * is a reserved character for JMX object names). (markt)
  • Code: Switch to using Charset rather than String to store encoding settings (including for configuration and for the Content-Type header) to reduce the number of places the associated Charset needs to be looked up. (markt)
