StackoverflowExcepton in Spring i18n Message ReloadableResourceBundleMessageSource

Question

I am including the i18n post in my Spring web application. For this, I have the code below inservlet.xml

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
        <property name="basename" value="classpath:messages/message"/>
        <property name="defaultEncoding" value="UTF-8"/>
    </bean>

After adding the above code, as soon as I hit my application in the browser, I got below the exception log:

SEVERE: Servlet.service() for servlet [default] in context with path [/ERP-Web] threw exception [Filter execution threw an exception] with root cause
java.lang.StackOverflowError
    at org.springframework.context.support.ReloadableResourceBundleMessageSource.getMergedProperties(ReloadableResourceBundleMessageSource.java:235)
    at org.springframework.context.support.ReloadableResourceBundleMessageSource.resolveCodeWithoutArguments(ReloadableResourceBundleMessageSource.java:176)
    at org.springframework.context.support.AbstractMessageSource.getMessageInternal(AbstractMessageSource.java:209)
    at org.springframework.context.support.AbstractMessageSource.getMessageFromParent(AbstractMessageSource.java:257)

where the last 2 lines are repeated 100 times and give me StackoverflowException.

Exactly the same exception occurs when I use a class ResourceBundleMessageSource.

My version of Spring 4.3.6.RELEASE.

Below is the content of my properties file

action.add.success = New {0} added successfully.
action.add.failure = Some error occurred in adding new {0}. Please try again later or contact administrator.
