Description:
Thanks to Java instrumentation support, it is now possible to deploy and operate Java SPI services within a LibreOffice extension.

This allows an extension to implement its own factory and easily operate it via its own javax.sql.rowset.spi service.

see: https://download.java.net/java/early_access/jdk26/docs/api/java.sql.rowset/javax/sql/rowset/spi/package-summary.html

> Standard classes and interfaces that a third-party provider must use to implement a synchronization provider.

In short, this will allow the jdbcDriverOOo extension to offer much more powerful JDBC services.

This is why I am insisting on backporting Java instrumentation support to LibreOffice 25.2.

pr#183280: https://gerrit.libreoffice.org/c/core/+/183280

Steps to Reproduce:
Unable to use Java SPI services in a LibreOffice extension written in Java 9 or higher with LibreOffice lower than 25.8.

Actual Results:
Unable to use Java SPI services in a LibreOffice extension written in Java 9 or higher with LibreOffice lower than 25.8.

Expected Results:
Be able to use Java SPI services in a LibreOffice extension written in Java 9 or higher with LibreOffice lower than 25.8.


Reproducible: Always


User Profile Reset: No

Additional Info:
The changes made to support Java instrumentation do not change the way Java works in LibreOffice.
Only extensions with corresponding xcu configuration files can use this new feature (ie: the jdbcDriverOOo extension)
