Use of Injection to provide Locale instances to components breaks when multiple Locales are configured as Spring Beans in AppContext

Certain components such as Select have java.util.Locale injected into it. With tapestry-spring-5.1.0.5, this creates a problem if you have Locale beans configured in your Spring application Context (externally maintained with tapestry.use-external-spring-context) as below.
<bean id="locale_US" class="java.util.Locale"><constructor-arg index="0" value="en" /><constructor-arg index="1" value="US" /></bean>
<bean id="locale_UK" class="java.util.Locale"><constructor-arg index="0" value="en" /><constructor-arg index="1" value="GB" /></bean>

This worked fine in Tapestry 5.0.18, but became a problem in 5.1. Currently, I managed to get 5.1.0.5 of Tapestry running with tapestry-spring-5.0.18, but this problem persists in tapestry-spring-5.1.0.5

Shouldn't tapestry be looking at the request to see which Locale it is for? Why is it going into Spring's application context?
