What’s new in Java 8 Update 381

Java 8 Update 381 comes with the following updates.

JDK 8u381 contains IANA time zone data 2023c

IANA (Internet Assigned Numbers Authority) maintains a database of time zone information that represents the history of local time for many locations around the globe. This database is periodically updated to reflect changes by political bodies to time zone boundaries, UTC offsets, and daylight-saving rules.

The following changes have been made with this release:

• Egypt now uses DST again, from April through October.
• This year Morocco springs forward on April 23, not April 30.
• Palestine delays the start of DST this year.
• Much of Greenland still uses DST from 2024 on.
• America/Yellowknife now links to America/Edmonton.
• tzselect can now use the current time to help infer the timezone.
• The code now defaults to C99 or later.
• Fix the use of C23 attributes.
• This release’s code and data are identical to 2023a.

The latest version of Java 8 Update 381 includes the time zone data from 2023g of the IANA database. You can learn more about this here.

Additional Characters for GB18030-2022 Support

The new GB18030-2022 standard was recently issued by the China National Standard body (CESI) which required a new Charset, hence required additional characters.

JDK accepts RSA Keys in PKCS#1 format

The JDK providers, like RSA KeyFactory.impl and SunRsaSign provider, now accept RSA public and private keys in the PKCS#1 format.

For a PKCS#1 RSA private key and public key, the RSA private or public key object must follow the PKCS#1 format and an encoding that adheres to the ASN.1 syntax.

Apart from these changes, this release also includes a few bug fixes. You can read more about these changes in the Java 8 update 381 release notes.

JDK vs JRE

Java Runtime Environment (JRE) is a piece of software installed on your computer that allows you to run applications developed in Java on your device. It provides certain libraries and other components required to run a Java program.

JRE also includes Java Virtual Machine (JVM), which is an engine also required to run Java applications on a machine. This engine is included in the JRE package and cannot be installed separately.

The Java Development Kit (JDK) is a development kit meant for developers, for developing applications in Java. It includes both the JRE and the JVM. If you are looking to create your own Java applets, then JDK is what you need. If you have JDK already installed on your device, you do not require to install JRE separately, unless a different version is required.

This should clear up if you want to install JRE or the JDK.
