Configuring Java 17 Compatibility

Temporary Measures for Java 17 Compatibility

Note

• Applicable up to version 1.1.17.
• This configuration is not required for version 1.2 and later.

Starting from Java 17, the Nashorn Script Engine previously used in this app has been removed. As a temporary workaround, please follow the steps below:

1. Download the Required Libraries

Download the following 5 JAR files from Maven Central:

• nashorn-core-15.3.jar
• asm-7.3.1.jar
• asm-commons-7.3.1.jar
• asm-tree-7.3.1.jar
• asm-util-7.3.1.jar

2. Place the Libraries in the Specified Directory

Copy the downloaded JAR files to the following directory:

/opt/atlassian/confluence/lib

3. Edit the setenv.sh File

To ensure the libraries are loaded at startup, edit the following file:

/opt/atlassian/confluence/bin/setenv.sh

Update the CATALINA_OPTS configuration by adding the JAR files to the classpath. Use the example below as a reference:

CATALINA_OPTS="${CATALINA_OPTS} ${JVM_SUPPORT_RECOMMENDED_ARGS} -DConfluenceHomeLogAppender.disabled=${CONFLUENCE_LOG_STDOUT} -cp /opt/atlassian/confluence/lib/nashorn-core-15.3.jar:/opt/atlassian/confluence/lib/asm-7.3.1.jar:/opt/atlassian/confluence/lib/asm-commons-7.3.1.jar:/opt/atlassian/confluence/lib/asm-tree-7.3.1.jar:/opt/atlassian/confluence/lib/asm-util-7.3.1.jar"

4. Restart Confluence

After completing the above steps, restart the Confluence service to apply the changes.

Notes

• These steps are a temporary measure. Please consider updating to the official solution when available.
• It is highly recommended to back up the original setenv.sh file before making any modifications.
