Thank you, Erik, for explanation.
Then I will go with the reflection solution. We can revert/simplify it in JDK
10 when jdk 9 will be used as boot JDK.
Thanks,
Vladimir

In theory it is possible to compile against and run on the exploded image
during the build, but I do not recommend it.
Igor is correct in the build team being against that design. The rationale is
that it adds a lot of complexity to the
build. The exploded image cannot be safely run until all java modules have been
compiled as it introduces races.
Maintaining the build with such a construct will be very brittle when other
changes are made. We did allow the gensrc
for jdk.vm.ci to run in this way for a short time, since it was only supported
on Linux x64, where these races are
rarer, but if this would ever need to be built on Windows, we would be in
trouble quickly. Luckily, jdk.vm.ci was able
to refactor away from needing this annotation processing for that module.
I certainly prefer the reflection solution proposed here, but find it sad that
it's needed.

When Graal is built as part of JDK it requires first to build an annotation
processor using boot jdk 8.
After JDK-8167180 changes Services class is referenced by annotation processor
but the code is using jdk 9 Module
API and it can't be used with jdk 8.
I left a comment in the bug: Permalink

Basically, it should be possible to use the newly built javac to compile the
annotation processors. Erik?
It’s not only about compilation it’s about running it on the bootstrap JDK,
which in currently 8.
igor
Can you paste or upload the .gmk file?
Use reflection instead of Module API and use code only for running with jdk 9.
Testing with JPRT and JDK build of Graal.
Thanks,
