Bug Reports
Hello.
I've a Spring Boot 3.4.5 / Spring 6.2.6 project that uses the old XML style to configure the application context.
While in Spring Boot 2.1.16 / Spring 5.1.8, the below was working fine:
appContext.xml
<context:property-placeholder ignore-resource-not-found="true" location="classpath:/testConfig.properties,/config.properties" />
<import resource="beanContext.xml" />beanContext.xml
<import resource="infrastructureContext.xml" />
<import resource="functionContext.xml" />
<!-- Other beans -->infrastructureContext.xml
<context:annotation-config />
<context:component-scan base-package="com.foo.dfi.hiku.commons.util.model.mdf" />
<bean id="bplCall" class="${bpl.class}">
<constructor-arg value="${bpl.server}" />
<constructor-arg value="${bpl.port}" />
<property name="Application" value="${bpl.name}" />
</bean>
<!-- Other beans -->in Spring Boot 3.4.5 fails with:

What I observed is that this is happening only for beans which have dynamic/property-based class names.
In the Spring migration documentation I cannot really spot anything useful, so your help would be highly appreciated here.
Kind regards and thanks.
