This is not possible, unfortunately, because of the dataflow semantics

So what does this mean? Has this change been permanently incorporated in
the JVM, or does the problem still exist? If the latter, how are you
planning to get around this limitation for Ozma?
Thanks,

No, the problem still exists. The modification was done by the
designers of FlowJava for their own implementation. It seems nobody on
the Java side sees a strong reason for this modification. It would be
tough to track every new JVM release to modify it and convince people
they should replace their original JVMs.
Ozma doesn't have this problem since it uses the Mozart emulator, not
the JVM. If Ozma can show Java people the usefulness of declarative
dataflow concurrency, then maybe the JVM would support it one day.
