That sort of proves my point, though. Spring support for GraalVM is ongoing and will likely be quite useable and mature out of the box.
The people jumping to Quarkus or Micronaut are more eager to chase the new shiny and are willing to spend the time debugging not-yet-mature stacks.
Edit: To be clear, the reply mentions fanboyism but we are talking about the maturity of a stack. Spring has been around for 20 years and is not going anywhere. Quarkus just reached 5.
The GraalVM is significantly more performant. Calling that "chasing the new shiny" redefines the meaning of the expression, which has historically been about side-grades for unclear advantages.
Especially considering that Springs support isn't full yet, and quarkus has been around for 5yrs now.
They're both production ready stacks though, really strange to have spring fanboyism in 2024
If Rails is fast enough, I doubt plain old Java on a standard JVM is slower. We’re talking comprehensive and productive web stack, not raw speed, otherwise we go back to the Go and Rust case.
I highly doubt that.
The real reason is likely more about the GraalVM, which spring hasn't supported until very recently. (And still only with caveats)
