That's just the same phenomenon - "not certified for a later Java" means that someone was unwilling to move to that later Java until it was EOLed.

Why don't the vendors certify for the later Java in anything less than five years?

It's the same question. Pushing it back one level doesn't answer it.

Usually app server versions and specific JVM versions are tied.

It is even in the specs.

Java EE 6 spec:

This specification requires that containers provide a Java Compatible™ runtime environment, as defined by the Java Platform, Standard Edition, v6 specification (Java SE).

Java EE 5 spec:

This specification requires that containers provide a Java Compatible™ runtime environment, as defined by the Java 2 Platform, Standard Edition, v5.0 specification (J2SE).

J2EE 1.4 spec:

This specification requires that containers provide a Java Compatible™ runtime
environment, as defined by the Java 2 Platform, Standard Edition, v1.4 specification
(J2SE).

J2EE 1.3 spec:

This specification requires that containers provide a Java Compatible™ runtime
environment, as defined by the Java 2 Platform, Standard Edition, v1.3 specification
(J2SE).
