Known Side Effects

Refer to Regression List for changes with negative effects.
  • If java.lang.OutOfMemoryError: Java heap space exception occurs on IBM i,  increase the Java heap size in /qibm/ProdData/InstallationManager/eclipse/tools/imcl.ini.
    • Change -Xmx512m to -Xmx1024m
  • If a WebSphere application running behind a HTTP proxy server (such as IBM HTTP Server with the WebSphere WebServer Plug-in) 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.
    Instructions to set HttpDispatcher custom properties in WebSphere Liberty are here and here.
     
  • Behavior changed in endpoint identification enabled on LDAPS connections.  See details for more information.
  • Known issue with illegal instruction on AIX when using the healthAnalyzer-1.0 feature with WebSphere Liberty and Java 8 SR5 FP15, FP16, or FP17. See this link for details.
  • Change in IBM WebSphere Java unrestricted policy files. See this link for details.
  • 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.
