Introduction
I've come across an unexpected error caused by calling

in an Netbeans Ant application that is being updated to Netbeans 15 and jdk 17 from netbeans 12 and jdk11 version.

WARNING [org.netbeans.core.modules]: Use of OpenIDE-Module-Class: Loader in com.adminserver.asgraphicrulesidemodule is obsolete.

I tried below options as per forms : updated class paths with arguments " --add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.util.concurrent=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED"

Updated spring and Jakarta and maven version as per compatibility of jdk 17. updated NetBeans modules as per NetBeans 15 supports.

Could you please help me to resolve this issue.

Thanks & Regards,
Abdul Ameer.
