As gh-28624 supports only static boolean fields, we still
need a few classes to be initialized at build time.
Such explicit configuration should be in theory avoidable,
so we will work with the GraalVM team to see if this can be
fixed, see for example
https://github.com/oracle/graal/issues/4673
for HttpStatus.
See gh-28624
This commit leverages a subset of @philwebb initial experimentation
to compute at build time the value of specific boolean static fields
in native images. This enhancement is implemented for now as a
GraalVM feature.
The goal here is to keep an optimized footprint via build time code
removal without leveraging build-time class initialization which is known
for the blocking compatibility issues it introduces due to its viral nature.
For now, the static fields initialized at build time with native are:
- NativeDetector#imageCode
- Fields with a name ending by "Present" in "org.springframework" package
typically used for classpath check with ClassUtils#isPresent
Closes gh-28624
