There is an SVM feature that allows one to instruct SVM to include certain 
resource bundles when generating an image. I have implemented it in Oct 2015 
and as far as I can see, it is still ready for use.

I am not however sure how to trigger that feature on in the GraalVM @ 0.20 
build. It gets triggered by @RequiredFeature({ResourcesFeature.class}) in the 
tests I have provided...

Btw. I have implemented that SVM feature based on my previous work of [getting 
Javac running on top of Bck2Brwsr](http://dew.apidesign.org/dew/). Michel, 
looks like you are trying to get Javac running on top of SVM. That is great, 
but I am afraid it won't work out of the box. 

Here is [the list of JDK classes that I had to additionally implement]
(https://github.com/jtulach/bck2brwsr/compare/release-0.8...release-0.8.1) to 
get Javac running on my restricted JVM:

bck2brwsr$ git diff release-0.8...release-0.8.1 | grep ^diff.*rt/emul/compact 
| cut -f 3 -d " " | cut -f 2- -d / | grep -v /test/

Apart from some missing implementations, the biggest problem is going to be 
the annotation processing. Javac is using java.lang.reflect.Proxy to 
dynamically create implementations of annotation classes before passing them 
to annotation processors. That is something SVM can't do at the moment. On the 
other hand annotation processors are supposed to be loaded dynamically and 
that will not work either...
