Known issues |
- If a WebSphere application running behind a HTTP proxy server begins experiencing failures with client certificate based authentication, or if client IP addresses or connection information are reported incorrectly as those of the proxy server, then it might be necessary to configure the "trustedSensitiveHeaderOrigin" custom property. On WebSphere Liberty, "trustedSensitiveHeaderOrigin" is configured as an HttpDispatcher custom property, and on traditional WebSphere the property is be configured as an HTTP channel custom property. This property has a default value of "none", and it also accepts value a of "*" (all), or a comma-separated list of IP addresses. For a secure deployment in which proxy servers are used, the "trustedSensitiveHeaderOrigin" property should be configured with a comma-separated list of IP addresses corresponding to those of any WebSphere-aware proxy servers in front of the WebSphere server.
Instructions to set HttpChannel custom properties in traditional WebSphere are here [1]
Instructions to set HttpDispatcher custom properties in WebSphere Liberty are here [2] and here [3]

[3] https://www.ibm.com/support/knowledgecenter/beta/en/SSEQTP_liberty/com.ibm.websphere.liberty.autogen.nd.doc/ae/rwlp_config_httpDispatcher.html - Behaviour changed in endpoint identification enabled on LDAPS connections. See details for more information.
- See Database changes for Java Batch in 18.0.0.1
- There is a behavior change in java.util.zip.ZipFile.getEntry() from IBM SDK V8 SR4 FP10. With this release, the name of the ZipEntry instance returned from java.util.zip.ZipFile.getEntry() always ends with / for any zip directory entry. To revert to the previous behavior, set the system property jdk.util.zip.ensureTrailingSlash to "false". See here for details.
