Hello everyone, I'm working on the SCJD now. I have read the implementation of suncertify.db.Data and I think the code is inefficient. (For example, I can use Read Write Lock to substitute the synchronized block, and I can use NIO's new method). Can I change the implementation or I have to blindly accept the code?
