add varags constructor for ClassPathXmlApplicationContext and FileSystemXmlApplicationContext [SPR-6849]

[spring-projects-issues]

Michael Isvy opened SPR-6849 and commented

Currently the syntax for those constructors is a little verbose:

new ClassPathXmlApplicationContext(new String[] {
        "com/acme/dao/dao-config.xml", "com/acme/service/service-config.xml"} );

Now that Spring 3.0 uses Java 5+ syntax, it would be simpler if we could take advantage of varags as follows:

new ClassPathXmlApplicationContext("com/acme/dao/dao-config.xml", "com/acme/service/service-config.xml");

As discussed, ClassPath/FileSystemXmlApplicationContext and also (Xml)BeanDefinitionReader use varargs where possible now. This was a bit of an oversight in 3.0 GA, since we are trying to use varargs as far as the signatures remain compatible - even if we can't consistently use varargs across all signature variants of a class (e.g. because there are further parameters after the array parameter).
