Remove instance suppliers in bean definitions and depend instead
on reflection. This allows the AOT engine to correctly process
the definitions.
Fixes gh-33763
GraalVM code reachability algorithm is not able to evaluate at build
time that ENABLED static field is always false in a native image,
shipping unreachable code.
Before this commit, building a native image with -H:+PrintAnalysisCallTree
shows that the following methods are included:
- BackgroundPreinitializer$1.<init>(BackgroundPreinitializer):void
- BackgroundPreinitializer$1.run():void
- BackgroundPreinitializer$1.runSafely(Runnable):void
- BackgroundPreinitializer$CharsetInitializer.run():void
- BackgroundPreinitializer$ConversionServiceInitializer.run():void
- BackgroundPreinitializer$JacksonInitializer.run():void
- BackgroundPreinitializer$MessageConverterInitializer.run():void
- BackgroundPreinitializer$ValidationInitializer.run():void
- BackgroundPreinitializer.<clinit>():void
- BackgroundPreinitializer.getOrder():int
- BackgroundPreinitializer.onApplicationEvent(ApplicationEvent):void
- BackgroundPreinitializer.onApplicationEvent(SpringApplicationEvent):void
- BackgroundPreinitializer.performPreinitialization():void
After this commit, only those are included:
- BackgroundPreinitializer.<clinit>():void
- BackgroundPreinitializer.getOrder():int
- BackgroundPreinitializer.onApplicationEvent(ApplicationEvent):void
- BackgroundPreinitializer.onApplicationEvent(SpringApplicationEvent):void
See gh-33240
SharedMetadataReaderFactoryContextInitializer exposes an additional
bean post processor that is only relevant when parsing the bean
factory, auto-configurations in particular. Given that this does not
happen in an AOT-optimized context, this commit excludes the bean
and makes sure the initializer does not do anything at runtime.
Closes gh-33216
AllEncompassingFormHttpMessageConverter already initializes
Jackson ObjectMapper. This commit updates BackgroundPreinitializer
in order to not run JacksonInitializer when
MessageConverterInitializer already takes care of initializing
ObjectMapper.
