The foo.bar is 1, the foo.foo is 2, and the bar is “foo”. The following construct:

<property name="boo" value="${${bar}.foo}">

used to work with Spring-4, setting property boo to 2.

But with Spring-5.x it is not expanded at all — the property boo is assigned the entire literal expression-string instead.

What’s the simplest fix here, without restructuring the underlying Java-code?
