January 19, 2021
The full version string for this update release is 1.8.0_281-b09 (where "b" means "build"). The version number is 8u281.
JDK 8u281 contains IANA time zone data version 2020d. 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 8u281 are specified in the following table:
JRE Family Version | JRE Security Baseline (Full Version String) |
---|---|
8 | 1.8.0_281-b09 |
7 | 1.7.0_291-b09 |
Oracle recommends that the JDK is updated with each Critical Patch Update (CPU). 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 8u281) be used after the next critical patch update scheduled for April 20, 2021.
Java SE Subscription customers managing JRE updates/installs for large number of desktops should consider using Java Advanced Management Console (AMC).
For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u281) on May 15, 2021. 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 23.1.2 JRE Expiration Date in the Java Platform, Standard Edition Deployment Guide.
A new -groupname
option has been added to keytool -genkeypair
so that a user can specify a named group when generating a key pair. For example, keytool -genkeypair -keyalg EC -groupname secp384r1
will generate an EC key pair by using the secp384r1
curve. Because there might be multiple curves with the same size, using the -groupname
option is preferred over the -keysize
option.
The Apache Santuario library has been upgraded to version 2.1.4. As a result, a new system property com.sun.org.apache.xml.internal.security.parser.pool-size
has been introduced.
This new system property sets the pool size of the internal DocumentBuilder
cache used when processing XML Signatures. The function is equivalent to the org.apache.xml.security.parser.pool-size
system property used in Apache Santuario and has the same default value of 20.
The "certificate_authorities" extension is an optional extension introduced in TLS 1.3. It is used to indicate the certificate authorities (CAs) that an endpoint supports and should be used by the receiving endpoint to guide certificate selection.
With this JDK release, the "certificate_authorities" extension is supported for TLS 1.3 in both the client and the server sides. This extension is always present for client certificate selection, while it is optional for server certificate selection.
Applications can enable this extension for server certificate selection by setting the jdk.tls.client.enableCAExtension
system property to true
. The default value of the property is false
.
Note that if the client trusts more CAs than the size limit of the extension (less than 2^16 bytes), the extension is not enabled. Also, some server implementations do not allow handshake messages to exceed 2^14 bytes. Consequently, there may be interoperability issues when jdk.tls.client.enableCAExtension
is set to true
and the client trusts more CAs than the server implementation limit.
Starting from macOS Catalina 10.15, applications do not have access to the Desktop, Documents and Downloads folders. So, if you use JavaControlPanel app to access files at the locations specified above, (such as load certificates from the Downloads folder) you must either move the files to another location or grant the required permissions to the JavaControlPanel app.
The steps to required to grant the permissions to JavaControlPanel are provided below:
1. On your Mac, open the Apple menu, click System Preferences, click Security & Privacy, then click Privacy.
2. Select Full Disk Access and click +.
3. In Applications, navigate to the System Preferences app (Applications > System Preferences), and click Open.
Note: You must grant permissions to the System Preferences app because the JavaControlPanel app is a part of that application on macOS.
The JDK update incorporates tzdata2020d. The main change is
Please refer to https://mm.icann.org/pipermail/tz-announce/2020-October/000062.html for more information.
The JDK update incorporates tzdata2020c. The main change is
Please refer to https://mm.icann.org/pipermail/tz-announce/2020-October/000060.html for more information.
Following the JDK's update to tzdata2020b, the long-obsolete files named pacificnew
and systemv
have been removed. As a result, the "US/Pacific-New" Zone name declared in the pacificnew
data file is no longer available for use.
Information regarding this update can be viewed at https://mm.icann.org/pipermail/tz-announce/2020-October/000059.html
This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update.
