Infinite loop in bean creation when placeholder used for bean name [SPR-5419]

[spring-projects-issues]

Dave Syer opened SPR-5419 and commented

If I use a placeholder to create the bean name alias from the name= attribute, there is an infinte loop in the bean creation (Spring never comes back from creating the application context). Example:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"
xmlns:context="http://www.springframework.org/schema/context">

<bean id="string" name="${string.name}" class="java.lang.String">
	<constructor-arg value="${string.value}" />
</bean>

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
	<property name="properties">
		<value>
		string.value=foo
		string.name=string
		</value>
	</property>
</bean>

</beans>
If the placeholder is not used for the name= (or if the alias is different from the id) then everything is fine.

Good catch! We did check for alias/name equality when registering an alias but not after placeholder resolution of an alias value. Fixed as of 3.0 M2.
