Debugging showed that a construct like
for (final Object bean : beans) {
applicationContext.registerBean(
bean.toString(),
(Class<Object>) bean.getClass(),
() -> bean
);
}
triggers the error while a construct like
for (final Object bean : beans) {
final Supplier<?> supplier = () -> bean;
applicationContext.registerBean(
bean.toString(),
(Class<Object>) bean.getClass(),
supplier
);
}
does not trigger it.
Minimal test class for reproduction:
package test;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.StaticApplicationContext;
public final class DummyAutowirer {
private DummyAutowirer() {}
public static ApplicationContext createContextForBeans(final List<Object> beans) {
final StaticApplicationContext applicationContext = new StaticApplicationContext();
for (final Object bean : beans) {
applicationContext.registerBean(
bean.toString(),
(Class<Object>) bean.getClass(),
() -> bean
);
}
return applicationContext;
}
}
