V8.3.1 Error when comparing versions with embedded macros (e.g. table of contents)

Question

After upgrading Confluence Server to 8.3.1 when ew compare versions of pages with embedded macros we get the error below.

Cause

Method "execute" failed for object com.atlassian.confluence.pages.actions.DiffPagesByVersionAction@6d632991

class org.outerj.daisy.diff.helper.CleanBrokenAttributeQNamesHandler (in unnamed module @0x6bfcdbc8) cannot access class com.sun.org.apache.xml.internal.utils.XML11Char (in module java.xml) because module java.xml does not export com.sun.org.apache.xml.internal.utils to unnamed module @0x6bfcdbc8

It works !!!.  Thanks and appreciate for your help.  I am using Data Centre for upgrading Confluence from 8.4.0 to version 8.5.2 LTS and Open JDK 17.0.7.  I need to add another statements in setenv.sh to make it displays as below

CATALINA_OPTS=" --add-modules java.se --add-exports java.base/jdk.internal.ref=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.nio=ALL-UNNAMED --add-opens java.base/sun.nio.ch=ALL-UNNAMED --add-opens java.management/sun.management=ALL-UNNAMED --add-opens jdk.management/com.sun.management.internal=ALL-UNNAMED --add-opens=java.base/sun.util.calendar=ALL-UNNAMED ${CATALINA_OPTS}"
CATALINA_OPTS="-Datlassian.recovery.password=Password ${CATALINA_OPTS}"

Note: the second option is used with recovery_admin user and only modify before executing the command: sudo /usr/bin/systemctl start confluence   and only on sandpit server for testing purpose.

I found a new setting in setenv.sh. Please check, if you have this setting:

# Add various JPMS arguments to allow Confluence to work on Java 17
CATALINA_OPTS="@$CATALINA_HOME/confluence/WEB-INF/jpms-args.txt ${CATALINA_OPTS}"

Our fault was, to reuse the old setenv.sh from Confluence 7 without this entry.

I didn't test java 17 with this option, but it sounds helpful.

I upgraded to 8.4.0 and Open JDK 17.0.7 (I believe it goes the Confluence version) and still got the error.  I am upgrading to 8.5.2 LTS and still have the same error.  Any help could be appreciated.
