JavaMemoryModel: On which JDK 1.4 VMs is "volatile access" already compliant with the proposed JDK 1.5 JMM?

Just wondering. If I were wanting to avoid using the "thread-local hack"
for the double-checked locking idiom on JDK 1.4 (just for those platforms
where JDK 1.4 volatile is 1.5 proposed-JMM compliant), how would I go about
determining the list of JDK 1.4 implementations that support the proposed
JMM semantics for volatile.

Thanks in advance.
