spring 3.1 bean name alias bug

[shenzhenguy]

the test code will go to a infinite loop. found the class org.springframework.core.SimpleAliasRegistry had a bug.

config:

<?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:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
	<bean id="a" class="test.TestAlias" />
	<bean id="b" class="test.TestAlias" />
	<bean id="c" class="test.TestAlias" />
	<bean id="d" class="test.TestAlias" />
	<bean id="e" class="test.TestAlias" />
	<alias name="a" alias="b"/>
	<alias name="b" alias="c"/>
	<alias name="c" alias="d"/>
	<alias name="d" alias="e"/>
	<alias name="e" alias="c"/>
</beans>

java code:

import org.springframework.context.support.FileSystemXmlApplicationContext;

public class TestAlias {
	public static void main(String[] args) {
		String config="config.xml";
		FileSystemXmlApplicationContext context=new FileSystemXmlApplicationContext(config);
		String[] als=context.getAliases("e");
		for(String str:als){
			System.out.println(str);
		}
		context.close();
	}
}

looks like you mean that

while(true) {
//some business code
}

is going to infinite loop. Of course it is cause it is coded that way.

I think spring should avoid the circle references, and he actually want to do this,but failed.
if the last line of config file is : <alias name="e" alias="d"/> or <alias name="e" alias="a"/> , Spring will throw Exception when in creation.
but for : <alias name="e" alias="c"/> or <alias name="e" alias="b"/> or <alias name="d" alias="b"/>,Spring cannot find the circle references, lead to getAliases() run into infinite loop.
