Hi Olivier, We have an issue in the tracker [1] regarding GraalVM, the CXF team have not invested much into GraalVM's native image support just yet but it seems like it becomes increasingly more important. Would you mind please to add the details to the existing ticket so we could understand the problems and scope better. Which version of GraalVM and Java (8 or 11) are you using? Thank you.
