Versions 2.0.0-M3 and later have problems parsing @ToolParam LocalTime with leading zero

Given following code:

package be.vdab.localtimetest;

import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.tool.annotation.Tool;
import org.springframework.ai.tool.annotation.ToolParam;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Component;

import java.time.LocalTime;

@SpringBootApplication
public class LocalTimeTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(LocalTimeTestApplication.class, args);
    }

}

@Component
class MyRunner implements CommandLineRunner {
    private final ChatClient chatClient;

    public MyRunner(ChatClient.Builder builder) {
        this.chatClient = builder.build();
    }

    @Override
    public void run(String... args) throws Exception {
        IO.println(chatClient.prompt("Is the shop open at 08:00 ?").tools(this).call().content());
    }

    @Tool(description = "Returns true if the shop is open at a certain time.")
    boolean open(
            @ToolParam(description = "The time for which you want to know if the shop is open.") LocalTime time) {
        var hour = time.getHour();
        return hour >= 10 && hour <= 18;
    }
}

This works on version 2.0.0-M2,

but does not work anymore on versions 2.0.0-M3 and 2.0.0-M4, giving an exception:
