PersistentStateComponent throws NPE (unable to find the solution)

Hello, I am the first time writer here. And if current topic should be in the another section - please move it.

I am getting exception

[  15939]  ERROR - .components.ComponentStoreImpl - null
java.lang.NullPointerException

My persistent component:

@State(name = "CodeReviewRemarks",
        storages = {
                @Storage(id = "default", file = StoragePathMacros.PROJECT_FILE),
                @Storage(id = "dir", file = StoragePathMacros.PROJECT_CONFIG_DIR + "/code-review-remarks.xml", scheme = StorageScheme.DIRECTORY_BASED)
        }
)
public class StorageComponent implements PersistentStateComponent {
    @Override
    public StorageComponent getState() {
        return this;
    }

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


And how it is registered in plugin.xml:

<extensions defaultExtensionNs="com.intellij">
        <applicationService id="CodeReview.StorageService"
                            serviceInterface="com.codereview.fs.StorageComponent"
                            serviceImplementation="com.codereview.fs.StorageComponent"/>
</extensions>


When i try to get this component like
StorageComponent compl = ServiceManager.getService(StorageComponent.class);

I've got the exception described at the beginning of this topic.

I was searching for the answers, but unable to get why i have this error.


Thanks.
