PersistentStateComponent with Application level cause Unable to save settings Error.

Before that, I succeeded to use Project level PersistentStateComponent already.

I just changed `plugin.xml` from

<projectService serviceImplementation="models.PersistentUser" />

<applicationService serviceImplementation="models.PersistentUser" />

And when I call

`ServiceManager.getService(PersistentUser.class)`, the error occured.

What else I should change codes if I want use Application Level PersistentStateComponent?

@State(
        name = "PersistentUser"
)
public class PersistentUser implements PersistentStateComponent<PersistentUser> {

  ...

@Nullable
@Override
public ServiceUser getState() {
    return this;
}

@Override
public void loadState(@NotNull ServiceUser state) {
    XmlSerializerUtil.copyBean(state, this);
}
}

This is my code.

<idea-plugin>
    ...
    <extensions defaultExtensionNs="com.intellij">
        <applicationService serviceImplementation="models.PersistentUser" />
        ...
    </extensions>

This is my plugin.xml.

And the code below has error.

ServiceManager.getService(PersistentUser.class);
