java.lang.NoSuchMethodError when calling a class that extends org.springframework.web.util.CookieGenerator from Spring 2 but that it is been used in Spring 3. [SPR-6942]

[spring-projects-issues]

jose antonio perez garcia opened SPR-6942 and commented

public class TestCookieGenerator extends CookieGenerator {

private static final int COOKIE_MAX_AGE = 365 * 24 * 60 * 60;

public TestCookieGenerator() {
    setCookieName(COOKIE_NAME);
    setCookieMaxAge(COOKIE_MAX_AGE);
}

}

TestCookieGenerator is been compiled using spring 2.5.6 which setCookieMaxAge(...) use an int in Spring 2.5.6 but this has change to be an Integer in Spring 3.

This doesn't seems to be a problem of autoboxing in Java. The problem comes up when a project that uses spring 3,it uses the library where the TestCookieGenerator has been compiled using spring 2.5.6. Because spring uses reflection to instantiate beans and reflection doesn't manage autoboxing(It is done at compilation time), that produce the next exception "java.lang.NoSuchMethodError: org.springframework.web.util.CookieGenerator.setCookieMaxAge(I)V".

Hi, is there any progress about this one?. It break the runtime compatibility between Spring 2 and 3. If a library was compilated against Spring 2 it cant't be used in a project that use Spring 3 and vice versa. Its not needed to extend the class, every class that explicitly call the method setCookieMaxAge reproduce the problem.

I am resolving this issue as invalid as it is now outdated.
