Spring Boot 3.2.x + Drools 7.73 + JDK 21: java.lang.classnotfoundexception: java.lang.compiler ⇐ JAVA

[Anonymous]

Я пытаюсь создать общий код для инициализации контейнера KIE на бизнес -процесс BPMN. Необходимо включить функциональность развертывания BPMN в контейнер KIE, чтобы выполнить эти конкретные экземпляры бизнес -процесса. Вот настройки:
зависимости градл:
implementation 'org.kie:kie-api:7.73.0.Final'
implementation 'org.kie:kie-dmn-api:7.73.0.Final'
implementation 'org.drools:drools-core:7.73.0.Final'
implementation 'org.jbpm:jbpm-flow:7.73.0.Final'
implementation("org.jbpm:jbpm-bpmn2:7.73.0.Final")
implementation("org.drools:drools-compiler:7.73.0.Final")
implementation 'org.jbpm:jbpm-flow-builder:7.73.0.Final'
implementation 'org.kie:kie-spring:7.73.0.Final'

Пример кода:
BpmnProcess process = bpmnProcessRepository.findByProcessId(processId);
if (process != null) {
String bpmnProcess = StringEscapeUtils.unescapeCsv(process.getBpmnXml());

BPMN2ProcessProvider provider = BPMN2ProcessFactory.getBPMN2ProcessProvider();
if (provider == null) {

throw new IllegalStateException("BPMN2ProcessProvider is not initialized. Ensure jbpm-flow-builder is on the classpath.");
} else {
System.out.println("BPMN2ProcessProvider is properly initialized.");
}

KieServices kieServices = KieServices.Factory.get();
String groupId = "com.example.kie";
String artifactId = "dynamic-process";
String version = "1.0.0";
ReleaseId releaseId = kieServices.newReleaseId(groupId, artifactId, version);
KieFileSystem kieFileSystem = kieServices.newKieFileSystem();
kieFileSystem.write("src/main/resources/process.bpmn", bpmnProcess);

kieServices.newKieBuilder(kieFileSystem).buildAll();
kieContainer = kieServices.newKieContainer(releaseId);
}

Проблема: bpmn2pocessprovider всегда инициализируется как NULL, и я не мог найти четкую документацию об этом. Пожалуйста, поделитесь любым рабочим образцом для использования динамических форматов BPMN с jbpm
