The full version string for this update release is 11.0.14+8 (where "+" means "build"). The version number is 11.0.14.
This release is intended as a bugfix release, to fix compatibility problems and typos reported since 2021b was released.
The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 11.0.14 are specified in the following table:
|JRE Family Version||JRE Security Baseline (Full Version String)|
Oracle recommends that the JDK is updated with each Critical Patch Update. In order to determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.
Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins. It is not recommended that this JDK (version 11.0.14) be used after the next critical patch update scheduled for April 19, 2022.
SunPKCS11 provider adds new provider configuration attributes to better control native resources usage. The SunPKCS11 provider consumes native resources in order to work with native PKCS11 libraries. To manage and better control the native resources, additional configuration attributes are added to control the frequency of clearing native references as well as whether to destroy the underlying PKCS11 Token after logout.
The 3 new attributes for SunPKCS11 provider configuration file are:
destroyTokenAfterLogout(boolean, defaults to false)
If set to true, when
java.security.AuthProvider.logout() is called upon the SunPKCS11 provider instance, the underlying Token object will be destroyed and resources will be freed. This essentially renders the SunPKCS11 provider instance unusable after
logout() calls. Note that a PKCS11 provider with this attribute set to
true should not be added to the system provider list since the provider object is not usable after a
logout() method call.
cleaner.shortInterval(integer, defaults to 2000, in milliseconds)
This defines the frequency for clearing native references during busy period (such as, how often should the cleaner thread processes the no-longer-needed native references in the queue to free up native memory). Note that the cleaner thread will switch to the 'longInterval' frequency after 200 failed tries (such as, when no references are found in the queue).
cleaner.longInterval(integer, defaults to 60000, in milliseconds)
This defines the frequency for checking native reference during non-busy period (such as, how often should the cleaner thread check the queue for native references). Note that the cleaner thread will switch back to the 'shortInterval' value if native PKCS11 references for cleaning are detected.
Two new system properties have been added. The system property,
jdk.tls.client.disableExtensions, is used to disable TLS extensions used in the client. The system property,
jdk.tls.server.disableExtensions, is used to disable TLS extensions used in the server. If an extension is disabled, it will be neither produced nor processed in the handshake messages.
The property string is a list of comma separated standard TLS extension names, as registered in the IANA documentation (for example, server_name, status_request, and signature_algorithms_cert). Note that the extension names are case sensitive. Unknown, unsupported, misspelled and duplicated TLS extension name tokens will be ignored.
Please note that the impact of blocking TLS extensions is complicated. For example, a TLS connection may not be able to be established if a mandatory extension is disabled. Please do not disable mandatory extensions, and do not use this feature unless you clearly understand the impact.
The following root certificate from Google has been removed from the
+ alias name "globalsignr2ca [jdk]" Distinguished Name: CN=GlobalSign, O=GlobalSign, OU=GlobalSign Root CA - R2
The ZIP file system provider has been changed to reject existing ZIP files that contain entries with "." or ".." in name elements. ZIP files with these entries cannot be used as a file system. Invoking the
java.nio.file.FileSystems.newFileSystem(...) methods throw
ZipException if the ZIP file contains these entries.
IANA Time Zone Database, on which JDK's Date/Time libraries are based, has made a tweak to some time zone rules since 2021c. Note that since this update, some of the time zone rules prior to the year 1970 have been modified according to the changes which were introduced with 2021b. For more detail, refer to the announcement of 2021b
A new JNDI environment property
“com.sun.jndi.ldap.tls.cbtype” has been added to enable TLS Channel Binding data in LDAP authentication over SSL/TLS protocol to the Windows AD server. A possible value is
“tls-server-end-point” - Channel Binding data is created on the base of the TLS server certificate. See the module description of the
This release reverts the behavior of SSLSocketImpl and SSLTransport introduced by JDK-8196584. SocketException will now be thrown as is instead of being suppressed into an SSLException.
This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update. For a more complete list of the bug fixes included in this release, see the JDK 11.0.14 Bug Fixes page.
