Hi, Let me clarify that this repo: https://github.com/tomitribe/graalvm-microprofile <https://github.com/tomitribe/graalvm-microprofile>
Is just to play around with the polyglot features of GraalVM. Building TomEE native images will be another story. I did try that when I was playing with the other repo and there are a lot of things that fail. This is not only about TomEE, but also about all the libraries used in TomEE itself. To be able to build to native image, you would need to comply with Substrate VM limitations stated here: https://github.com/oracle/graal/blob/master/substratevm/LIMITATIONS.md <https://github.com/oracle/graal/blob/master/substratevm/LIMITATIONS.md> For instance, projects like Quarkus or Micronaut removed all reflection calls and resolve these at compile time rather than runtime. While it is possible to instruct GraalVM about some reflection usage when doing the native image, I believe it won’t be enough in TomEE case and most likely some portions would need to be reimplemented. I have no idea what would be the effort involved in a task like this. It is not trivial.
