On Tuesday night in Belgium at Devoxx I'm asking the question "Is there room for one more library in JDK 9"?
With JDK 9 full of modules, and the long wait until JDK 10 for more interesting things like value types, I pose this question to the community to ask what would you add to JDK 9 if you could?
But, I'm asking more than that. Any additional work for JDK 9 would have to be led by someone outside Oracle capable of drawing together a community. And whatever it is it would need to be tightly focussed - the timescale available is limited.
Think of something that could be expressed in 20 classes or less. Involves only code and no library or JVM changes. Something that the JDK doesn't have, but you think it should. Think about whether you'd put in your time to try and make it happen.
But also think about whether your idea should be in the JDK? Is it better as an external library? What makes it necessary to be in the JDK, especially a modularized JDK? Will Oracle's Java stewards support the idea?
As an example, I'll put forward Joda-Convert, a very small and simple library that provides a mechanism to convert and round-trip a simple object (like a VALJO) to a formatted string, ideal for use in serialization, such as JSON or XML (and noting that JSON is coming to JDK 9...). I'm sure that if you're reading this, you've got some other ideas!
If you've got any thoughts, ideas, or want to suggest something, please add a comment. But remember the rules above - there is no free lunch here. Are you willing to take a lead on your idea?
