Please change the build to allow Java Shared classes cache to be fully supportd.

Describe the bug

Some Java classes can be loaded into the Java Shared Classes Cache - and so speed up startup.
Spring has been built with jar:nested.... which is not supported in Java SCC.

Please can you build APIML to use the CLASSIC loader. See

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.2-Release-Notes#nested-jar-support

There is an issue raised against Java eclipse-openj9/openj9#21249
but I do not expect this to be generally available for a couple of years ( because the z/OS releases come out ever couple of years.)

I expect to reduce the startup time by about 30 seconds (out of 6 minutes) for the component. If this works, we can change the other components and reduce their startup times.

I've tried to build it myself, but could not find where to change it.

Ive been working for a few months with Sean and Jakub on this problem
