Native version of webflux/r2dbc failed

[operrin]

Hello,

my setup is:

• java:
  openjdk 17.0.5 2022-10-18
  OpenJDK Runtime Environment GraalVM CE 22.3.0 (build 17.0.5+8-jvmci-22.3-b08)
  OpenJDK 64-Bit Server VM GraalVM CE 22.3.0 (build 17.0.5+8-jvmci-22.3-b08, mixed mode, sharing)
• platform:
  Mac M1
• os:
  12.6.1

the following fresh new SB3 project [1] compiles and runs without any problems when produced with
gradle bootJar.

When compiled with gradle nativeCompile, it fails for the following route: http:8082/intervenants.
POST, DELETE, PUT or GET intervenants/{id} work fine.

I'm not sure if the probem is related to SB3 or to a GraalVM problem (last line of the exception report):

It looks like a bug in the proxying that's necessary to honour the use of @Transactional on IntervenantHandler. We'll ask the Framework team to take a look.

Hi,

the problem is still reproducible with the new 3.0.2.

Thanks
