Environment

  • Liferay DXP 7.3, 7.4 and Liferay DXP 2023/2024 Quarterly Release Self-Hosted environments operating with Elasticsearch version 7.17.19 with JDK 22.
  • Elasticsearch version 7.17.19 , versions 8.13.0/8.13.11 - with JDK 22.

Symptoms

1) Elasticsearch could abruptly stop with JDK 22

One or more Elasticsearch nodes could abruptly stop resulting in the following symptoms (list non-exhaustive):

2) Elasticsearch node would report a fatal error related to Java class Ljdk.internal.vm.FillerArray . For example:

Cause

The issue is being investigated by Elastic in java.lang.ClassCastException: class Ljdk.internal.vm.FillerArray; cannot be cast to class, after upgrading to 8.13.0.

The same issue is linked to this JDK issue which is currently under investigation: java.lang.ClassCastException: class Ljdk.internal.vm.FillerArray; cannot be cast to class java.nio.ByteBuffer (Ljdk.internal.vm.FillerArray; and java.nio.ByteBuffer are in module java.base of loader 'bootstrap').

Workaround

  • For Liferay Self-hosted environments: users can install and use JDK version 21.0.2 instead (see: Java (JVM) Verssion). A resolution is available (see below).
  • For Liferay Saas and Paas environments: No action required.

Resolution

Elasticsearch 7.17.20 will be bundled with JDK 21.0.2 (Downgrade the bundled JDK to JDK 21.0.2).

1 Elasticsearch 8.13.x is currently not a compatible search engine version for Liferay environments. The compatibilty testing is expected to take place in 2024 Q2.
