- 8.5.5.26
- MQDefaultSSLConfig ignored in 8.5.5.26
- For customers using mixed JDK environment, jvms running on JDK lower than 8.0.8.0 might be unable to open PKCS12 keystores due to an UnrecoverableKeyException after dmgr updates the keystore files: Unable to open PKCS12 keystores due to an UnrecoverableKeyException
- 8.5.5.25
- For customers using mixed JDK environment, jvms running on JDK lower than 8.0.8.0 might be unable to open PKCS12 keystores due to an UnrecoverableKeyException after dmgr updates the keystore files: Unable to open PKCS12 keystores due to an UnrecoverableKeyException
- 8.5.5.24
- WebSphere WebServer Plug-in: WebSphere web server plug-in changes to certificate hostname validation
- IBM HTTP Server: SSL ciphers using RSA key exchange are no longer enabled by default
- IBM HTTP Server: Configurations with SSLFIPSEnable and RSA Key Exchange based ciphers explicitly added will fail with SSL0212E if these ciphers are actually negotiated. RSA Key Exchange ciphers should not be added to a FIPS enabled configuration.
Failure to start the server if Java 2 Security is enabled with the following cause:
Caused by: java.security.ProviderException: Access denied ("java.util.PropertyPermission" "java.home" "read") at com.ibm.crypto.plus.provider.IBMJCEPlus.e(IBMJCEPlus.java:287)Solution: The following needs to be added to the java.policy file to resolve this issue.
grant codeBase "file:${java.home}/fips${com.ibm.fips.mode}/lib/ext/*" { permission java.security.AllPermission; };For customers using mixed JDK environment, jvms running on JDK lower than 8.0.8.0 might be unable to open PKCS12 keystores due to an UnrecoverableKeyException after dmgr updates the keystore files: Unable to open PKCS12 keystores due to an UnrecoverableKeyException
- 8.5.5.23
- The ability to administer DataPower appliances has been removed from the WebSphere Application Server Administrative Console. See details in PH50841.
- IBM HTTP Server: IBM HTTP Server now limits HTTP request bodies to 1 Gigabyte by default. Previously, there was no limit.
- The limit can be increased by using the LimitRequestBody directive. Users are encouraged to limit such increases using limited scope such as <Location> rather than changing it globally.
- 8.5.5.16
- If a WebSphere application running behind a HTTP proxy server (such as IBM HTTP Server with the WebSphere WebServer Plug-in) further configuration may be required to trust data from the proxy server. See Potential WebSphere Application Server problems when deployed behind a WebSphere-aware proxy server.
