With the new support of Java JDK 17 and 21 runtimes, Java 11 will no longer be supported for DXP runtime on 2024.Q3 or later. 

Liferay Workspace offers support for re-compiling custom modules on JDK 17 or 21.

What changed?

From Liferay DXP 2024.Q2 onwards, localizable object entry fields now default to the instance's language setting, replacing the previous user-language default.

Why was this change made? Is the new behavior better for users?

This change was implemented to ensure consistent language configuration. The new behavior is indeed better for users because:

• It prevents discrepancies that could occur when users with different language settings interacted with the same object entry fields.

• It provides a unified experience across all user interactions.

Who is affected?

Customers using or upgrading from versions prior to Liferay DXP 2024.Q2 are affected by this change.

How should I update my features or implementation to better adopt the breaking change?

To adapt to the new behavior:

• Check your existing localizable object entries' default language settings.

• Adjust these settings to match the instance language if needed.

This ensures consistent language defaults and creates a uniform experience for all users.

The AMBackwardsCompatibilityHtmlContentTransformer class was introduced in the Adaptive Media release (~7 years ago) to manage content created before Adaptive Media was implemented. This approach helped to avoid a costly upgrade at the time. However, since much time has passed and newer content no longer requires this processing, we are disabling the AM backward compatibility HTML content transformer by default.

The primary reason for this change is performance: the content transformer can consume significant CPU resources, especially under heavy traffic.

The content transformer can be enabled in Instance Settings > Adaptive Media if necessary.

The JVM java.locale.providers setting for DXP has been restored to the default value to account for the move to Java JDK 17 and 21.

Previously, DXP and Portal shipped with and recommended setting java.locale.providers=JRE,COMPAT,CLDR to provide consistent locale behavior for Java 8 and 11 since JRE was previously the default provider. With Java 17 and 21, JRE is now deprecated and the CLDR locale provider becomes the default and recommended provider. See further information from Oracle.

The new recommended value is java.locale.providers=CLDR,COMPAT as it is the new JVM default. The Liferay Tomcat bundles for 2024.Q4 will ship without this JVM property set, since we are using the default.

With this change the default provider, some locale information in the system might display with modified formatting. For example, a Date and Time display may have previously shown as “9/12/24 9:10 PM” but now displays as “9/12/24, 9:10 PM”. This is the expected result from moving to the latest Java locale provider that meets modern language standards.
