Re: [jakartaee-platform-dev] Batch+CDI integration: proposal to continue

Hi,

This is probably a tad premature but one way to reduce breaking backwards compatibility risks is saying @Inject in non-CDI beans will only work if CDI is enabled. It’s unlikely folks use more than one full scale DI framework at the same time (I have never seen a single case in 15+ years).

I'm afraid that the Batch spec now explicitly allows using any DI engine to instantiate Batch artifacts and inject other beans beyond those required by the spec. So if we say that @Inject only works with CDI it would already be a breaking change anyway, even though people rarely use Batch with another DI framework. So I would rather postpone this decision and introduce the braking change when we decide to support option 1.
