Yeah, that's an option, but it's a lot more work and has other possible impacts. Given the relatively low uptake of Java on z, we'd rather isolate the changes to Java-land. Andrew Rowley suggested: >NewDirectByteBuffer looks like it would allow you to allocate buffers from the JNI side (and therefore control the location in storage) and use them from Java. I don't know what the performance implications are. Not sure this helps, as the Java side has no relationship with the JNI other than calling it atomically. This seems more like it's for use in a cooperative/persistent environment, where the Java side is going to know more about the JNI side. But I'm no Java programmer (I don't even drink coffee), so maybe?
