AOT Repos treating booleans as integers

[RobMaskell]

Converting my app to Spring Boot 4, it runs as a native app and uses Spring Data JDBC so it's using the new aot repositories. I get some weird behaviour on a particular boolean field, it's boolean in the database, boolean in the object but something wants to play the Integer game.

I've created a minimal sample app that shows the issue. App will run fine in the IDE but a ./gradlew nativeRun will/should generate a stack trace like this one below. I run against postgres so you'll need a db called aottest with a user of the same name.

This seemed like a sensible project to report to but let me know if I've got the wrong one.

This is a GraalVM problem, see oracle/graal#12596.

[RobMaskell]

@mp911de thanks, didn't think to look on the other string data projects, and not confident enough in what was going on to report to graalvm. The reason I posted here was that it works fine on spring boot 3.5.7 with the same version of the native build tools.

I tried to use

tasks.named('processAot') {
	systemProperty 'spring.aot.repositories.enabled', 'false'
}

but that just changed the error to something similar but not exactly the same, so my spring boot 4 conversion seems blocked for now, not really an issue, I don't need it right away, just curious to try

[mp911de]

Have you tried setting spring.aot.data.accessors.enabled=false? With Spring Data 4.0, we additionally include generated bytecode for property accessors as classes (see com.example.demo.SheetsUser__Accessor_x7mayh.setProperty(Unknown Source)) that we've used previously only in JVM mode. You might need to upgrade to Spring Data Commons 4.0.1-SNAPSHOT for that matter and please let us know whether this approach works for you.

[RobMaskell]

@mp911de I tried it, thanks. I think that worked because I'm back to the spring security exception serialisation issues.

I had spring.aot.data.accessors.enabled=false commented out in build.gradle, the upgrade to commons 4.0.1-SNAPSHOT explains why it didn't work the first time I tried it
