-	Helidon ~~guys can use Ruby, JavaScript, Helidon can use WELD. Polyglot Context can be~~ in the ~~native~~-~~image~~.	+	[[Helidon]] is a microservices framework developed ''four meters away from me'' (my seat in [[Oracle]] Prague office). As such [[I]] felt as the natural fit for solving complex tasks that require understanding of both sides - the [[JavaEE]] landscape as well as the [[GraalVM]] internals.

		+	[[Helidon]] MP implements the [[MicroProfile]] specification based on various other standard [[JavaEE]] subspecifications including [[CDI]]. Getting [[Weld]] (the reference [[CDI]] specification) running on top of [[NativeImage]] is particularly tricky. Not only [[Weld]] dynamically scans for various annotations, but it also dynamically emits [[bytecode]] for its helper classes during runtime. Solving this required more insight into [[JavaEE]] than available among compiler engineers - not that [[I]] had it initially, but the close co-operation with Tomáš Langer (the [[Helidon]] lead engineer) helped us move forward. Tomáš prepared various trivial [[CDI]] sample projects and [[I]] was then able to get them running on [[NativeImage]] by writing a dedicated '''WeldFeature'''. Once the initial road block was gone the [[Helidon]] team was able to move forward on their own and get their enhanced [[Weld]] running on top of [[NativeImage]].
		+
		+	[[Helidon]] 2.0 [https://medium.com/helidon/announcing-helidon-2-0-19c245f5488a was released] on June 24, 2020. It's [[MicroProfile]] edition (including compatible [[CDI]] implementation) works with [[NativeImage]].
