Java 5+ upgrade of core container API and implementation [SPR-5231]

[spring-projects-issues]

Juergen Hoeller opened SPR-5231 and commented

Spring 3.0 gives us the chance to upgrade the entire Spring API to Java 5+.

This issue is tracking the upgrade effort in Spring's core packages:

• org.springframework.aop
• org.springframework.beans
• org.springframework.context
• org.springframework.core
• org.springframework.util

Will you be introducing generic signatures? Many of these classes still use raw types all over the place.

Have you been looking at the actual (new) 3.0 repo at https://src.springframework.org/svn/spring-framework/trunk?

We are certainly not done with generifying the API yet... but plenty of it has been generified already.

Two further big commit bunches came in yesterday and tonight. The Java 5 code style update is 99% done now.

My apologies. Because this issue was Resolved well in advance of further commits, I thought all the commits were finished. My interest is looking to see how much generic signatures, like #9287, will make it into the core.

For example, this article says that instanceof operator should always use the unknown type <?> on a generic class. I think it's a good practice to follow:
