Yes. You could possibly also fabricate a "thread-safety layer" to the underlying SAIL system, if that is now not thread-safe. Need to study the issue in more depth, but the basic position is that Qi4j instances (new Energy4Java) are isolated from each other as much as is possible with the JVM. Only immutables static members should exist, nothing else shared, no threading issues should exist, and Rickard has also done a proof-of-concept (maybe production now) to have Qi4j instances as plugins inside a Qi4j application. That is the ambition level. If the "should"s above are not true, then that constitute bug(s) and should be fixed if found. So, what we have not had as a ambition level is to ensure the same for all systems we integrate with. But if solid usecases emerge we will look at them and try to ease-the-pain.
