JDK 8u111 contains IANA time zone data version 2016f. For more information, refer to Timezone Data Versions in the JRE Software.
The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 8u111 are specified in the following table:
|JRE Family Version||JRE Security Baseline (Full Version String)|
The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 8u111) will expire with the release of the next critical patch update scheduled for January 17, 2017.
For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u111) on February 17, 2017. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date.
New JCE Code Signing Root CA
In order to support longer key lengths and stronger signature algorithms, a new JCE Provider Code Signing root certificate authority has been created and its certificate added to Oracle JDK. New JCE provider code signing certificates issued from this CA will be used to sign JCE providers from this point forward. By default, new requests for JCE provider code signing certificates will be issued from this CA.
Existing certificates from the current JCE provider code signing root will continue to validate. However, this root CA may be disabled at some point in the future. We recommend that new certificates be requested and existing provider JARs be re-signed.
For details on the JCE provider signing process, please refer to the How to Implement a Provider in the Java Cryptography Architecture documentation.

Service Menu services
The lifecycle management of AWT menu components exposed problems on certain platforms. This fix improves state synchronization between menus and their containers.

Disable Basic authentication for HTTPS tunneling
In some environments, certain authentication schemes may be undesirable when proxying HTTPS. Accordingly, the Basic authentication scheme has been deactivated, by default, in the Oracle Java Runtime, by adding Basic to the
jdk.http.auth.tunneling.disabledSchemes networking property. Now, proxies requiring
Basic authentication when setting up a tunnel for HTTPS will no longer succeed by default. If required, this authentication scheme can be reactivated by removing
Basic from the
jdk.http.auth.tunneling.disabledSchemes networking property, or by setting a system property of the same name to "" ( empty ) on the command line.
jdk.http.auth.proxying.disabledSchemes networking properties, and system properties of the same name, can be used to disable other authentication schemes that may be active when setting up a tunnel for HTTPS, or proxying plain HTTP, respectively.

Restrict JARs signed with weak algorithms and keys
This JDK release introduces new restrictions on how signed JAR files are verified. If the signed JAR file uses a disabled algorithm or key size less than the minimum length, signature verification operations will ignore the signature and treat the JAR file as if it were unsigned. This can potentially occur in the following types of applications that use signed JAR files:
The list of disabled algorithms is controlled via a new security property, jdk.jar.disabledAlgorithms, in the
java.security file. This property contains a list of disabled algorithms and key sizes for cryptographically signed JAR files.
The following algorithms and key sizes are restricted in this release:
NOTE: We are planning to restrict MD5-based signatures in signed JARs in the April 2017 CPU.
To check if a weak algorithm or key was used to sign a JAR file, you can use the
jarsigner binary that ships with this JDK. Running jarsigner -verify -J-Djava.security.debug=jar on a JAR file signed with a weak algorithm or key will print more information about the disabled algorithm or key.
For example, to check a JAR file named
test.jar, use the following command:
jarsigner -verify -J-Djava.security.debug=jar test.jar
If the file in this example was signed with a weak signature algorithm like MD2withRSA, the following output would be displayed:
jar: beginEntry META-INF/my_sig.RSA
jar: processEntry: processing block
jar: processEntry caught: java.security.SignatureException: Signature check
failed. Disabled algorithm used: MD2withRSA
jar: done with meta!
jarsigner command will exit with the following warning printed to standard output:
"Signature not parsable or verifiable. The jar will be treated as unsigned. The jar may have been signed with a weak algorithm that is now disabled. For more information, rerun
jarsigner with debug enabled (
To address the issue, the JAR file will need to be re-signed with a stronger algorithm or key size.
Alternatively, the restrictions can be reverted by removing the applicable weak algorithms or key sizes from the jdk.jar.disabledAlgorithms security property; however, this option is not recommended. Before re-signing affected JAR files, the existing signature(s) should be removed from the JAR. This can be done with the zip utility, as follows:
zip -d test.jar 'META-INF/*.SF' 'META-INF/*.RSA' 'META-INF/*.DSA'
Please periodically check the Oracle JRE and JDK Cryptographic Roadmap at http://java.com/cryptoroadmap for planned restrictions to signed JAR files and other security components. In particular, please note the current plan is to restrict MD5-based signatures in signed JAR files in the April 2017 CPU.
To test if your JARs have been signed with MD5, add MD5 to the jdk.jar.disabledAlgorithms security property, ex:
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
and then run
jarsigner -verify -J-Djava.security.debug=jar on your JAR files as described above.

Warning message added to deployment authenticator dialog
A warning has been added to the plugin authentication dialog in cases where HTTP Basic authentication (credentials are sent unencrypted) is used while using a proxy or while not using SSL/TLS protocols:
"WARNING: Basic authentication scheme will effectively transmit your credentials in clear text. Do you really want to do this?"

Some events not available in JFR recordings on Windows
The following events are not available in the JFR recordings on Windows for release 8u111:
This is due to regression JDK-8063089 that was introduced in 8u111 with the changes for JDK-8162419. The fix for JDK-8063089 could not be included in the 8u111 release. It will be available in the next 8u111 BPR build and in the next public release.
JDK-8063089 (not public)
This release contains fixes for security vulnerabilities described in the Oracle Java SE Critical Patch Update Advisory. For a more complete list of the bug fixes included in this release, see the JDK 8u111 Bug Fixes page.
