> What do you specifically expect from Spring running on GraalVM?

Mostly performance gains you get from AOT. I think GraalVM ( or similar technologies) is going to be a game changer for all langs that compile to intermediary byte code.

Unfortunately, GraalVM does not compile Spring as Spring uses reflection a lot and GraalVM does not fully support reflection. https://github.com/oracle/graal/issues/348

Performance gains of GraalVM's AOT are drastically reduced startup time (1 ms for my Java/Kotlin command-line applications), elimination of JIT warmup time, and reduced memory footprint. For peak performance of a language as dynamic as Java, a JIT is hard to beat. Profile-guided optimizations will narrow the gap but are only available in GraalVM Enterprise Edition. Native executables also have a less sophisticated GC than HotSpot.

Thank you for sharing your knowledge. Its insights like this that make hn so awesome.
