This contains a small example of an attempt to build sources for an existing
module in the JDK (jdk.internal.vm.compiler) where the build process involves
running an processor for an
annotation (org.graalvm.compiler.serviceprovider.ServiceProvider)
that is defined both on the class path as well as in jdk.internal.vm.compiler.
I want only the class path instance to be found by the annotation processor.
Currently, it appears to find both copies:
> ./run.sh
TypeElement for org.graalvm.compiler.serviceprovider.ServiceProvider is null
Note: Multiple elements named 'org.graalvm.compiler.serviceprovider.ServiceProvider' in modules 'jdk.internal.vm.compiler, unnamed module' were found by javax.lang.model.util.Elements.getTypeElement.
My thought was that --patch-module=jdk.internal.vm.compiler=service/bin:impl/src would result in
ServiceProvider.class under service/bin overriding ServiceProvider.class from
jdk.internal.vm.compiler.
