Fixing the jcp – the server side java symposium

Posted on by
Reply

The official title of this session is “The Java Community Process – What’s broken and how to fix it”.  The panel is James Gosling, Patrick Curran (head of the jcp) and Reza Rahman (member of jcp expert groups and author of EJB in action)

What’s wrong

  • Some inherent because so many priorities and agendas. these predated Oracle
  • Apache Harmony TCK issue (Apache Geronomo doesn’t pay for TCK because non profit open source. The problem with Harmony is that it has restrictions). Reza would like to see it free, no strings attached after the lawsuit.
  • Patrick said Oracle is more forceful than Sun in that they make a stand rather than bicker forever
  • Reza said James is too bright but not practical enough :). He views Oracle as being more practical. Reza noted leading is hard and getting people to agree is hard. He views Oracle leading as a necessity because they have the resources to be a JSR lead.   James noted being a spec lead is a full time job even if things go smoothly.
  • In 2007, Oracle tried to create an organization so sun would have less power. Now that they are in charge, they want to retain ownership. Logical position at least.
  • Process issues -greater transparency so don’t have to be a JCP member for read only view
  • Reza views a big problem as lack of individual participation in the JCP. Reas the proceedings, blog, be spec leads, etc. Democracy is participatory [yes, but this isn’t a democracy, right after i wrote this Cameron noted SpringSource and Google are leading by example. Reza said that sounds like Microsoft. and it does.  Except that Sun copied from Spring extensively. James noted that innovation in the String class would be dangerous]

What could be better

  • Reza recognized it is hard to have an independent JCP. It requires resources, a way to move forward without veto bpower, etc
  • Patrick noted that all standards groups have these political obstacles because companies or countries have different interests. The fact that they are trying to work together is a good thing.
  • Patrick noted things are better than they look. Some groups have mailing lists that be read.  Oracle is looking at making things more open and expect to mandate transparency via an open mailing list. Similarly for formally tracking comments. The executive committee has been publishing minutes for several years.
  • Patrick noted they are looking at making it easier to join. In particular, creating a simpler legal agreement for non-spec lead roles
  • Patrick pointed out standards take time. It is more important to get it right than fast. It is avoiding unnecessary waste that matters

audience questions

  • Role of spec evangelist separate from spec lead?  Reza said don’t need formal role. Independents on JCP should blog and do this
  • More people shipping products dependent on platform?  oracle working on balance. Also looking at letting java user groups join so members can contribute
  • What can someone do to help without spending a lot of time?  Follow JSR interested in. Read the spec and comment without joining group. Mny JSRS are open source comments. Reza listed following jee articles on theserverside and javalobby and leave comments for actual jcp members to read and convey. Similarly for the comment period. [this was my question, a lot of the answers sound quite time consuming to me. Reza did list a short one which I appreciate]
  • Developers wait until something is stable to try it because working our own problems. By then it is late in the game to comment. Everyone agreed the proposed final draft and reference implementation IS that

java in flux – the server side java symposium

Oh look.  The ten line Oracle disclaimer is back.  At least this talk contains some forward looking statements where it makes sense to have the disclaimer.

Communication
Oracle recognizes they have issues with communicating late/poorly.  They have a culture of saying little and sticking to it.  Whereas Sun had more dialog.  They acknowledge it; will be interesting to see what happens.

Priority

Want to keep Java vibrant to keep making money.  Said will continue move to Open JDK.  Moving JRockit features to OpenJDK.

Other topics

  • Looking at support for multiple cores at the CPU level.  Think parallel collections and lambda/closures will be good candidates for paralleilization
  • Let ideas mature in more experimental languages
  • Reiterated pledge to backward compatibility
  • Covered what’s new in Java 7 at a high level – most I had heard before – the more lightweight garbage collector was new to me
  • Java 8 – more modularization, project lambda(closures), annotations on Java types and more small language enhancements
  • Java 9 – really speculative – forces on platform independence with hardware virtualization, better interoperatibility with non Java languages, improved data integration, improved device support
  • Looking to expand Java FX [surprised]

JEE

  • Want JEE 7 done before Java 8 comes out which is end of 2012
  • Looking at what can do for modularity in JEE 7 before “real” modularity comes out in Java 8
  • Compared Java to .NET.Azure including areas like Cloud and multiple language support where Microsoft doing better
  • Covered the problems it was designed to solve and how it got so big that it isn’t simple anymore. Going back to POJOs, dependency injection. [again making it sound like this stuff just sprung up from developer complaints]
  • Showed timeline from 1998 and J2EE 1.2.
  • Recognized innovation is occurring on the outside and the platform stewards/Oracle need to reuse that to avoid becoming irrelevant
  • Customers win when there is interoperability and vendor choice
  • Companies want to build internal clouds – solutions starting to be built on Java Also noted cloud gives new JEE roles of data center and tenant roles. (in addition to things like deployer) In addition, noted the existing JEE APIs need to become tenant aware. Such as how to discriminate within a table what rows are associated with what tenant in a JPA entity. Maybe in JEE 8

Ibm’s enterprise java for the future – the server side jack symposium

Enterprise java for the next decade – IBM’s take on one possibility for the future
Facts/industry trends

  • hitting the limit of Moore’s law, can add more CPUs , but not make existing ones significantly faster [surprised they didn’t bring up threading here]
  • Memory still rapidly increasing, disk capacity is growing, but not as fast
  • Hardware is getting smaller, cell phones/smart phones are now real computers, they aren’t special purpose operating systems anymore
  • Projects are becoming more complex
  • Data transformations more complex, new formats
  • Amount of information and # devices dealing with data rapidly growing – ip v4 full, RFID, gps, etc

speculation

  • More software will mean more jobs. But jobs I’ll require new skills for enterprise software
  • Need to simplify the enterprise platform with focus on making easy things easy and hard things possible
  • Class loader system to complex/ambiguous for the future
  • Number of technologies for a beginning JEE developer is too overwhelming and we keep adding to it
  • Don’t need two packages with same name for metadata [how balance backward compatibility without blowing up complexity?]. Eventually will have single definition with ONE XML file that controls metadata, similarly for annotations
  • Don’t think one injection model will be enough, but still need to collapse from what we have now
  • Expect concurrency and async workflows to change so defining at higher level
  • Brought up getting rid of the stuff that has been deprecated for a long time like BMP [sun never reveled anything, will Oracle?]

At this point I stopped taking detailed notes on the APIs. The gist of it is that the IBM speaker organized the APIs into groups and called the higher level one simpler. It is if you can get rid of what is there today and replace it with a general API. Of course 10 years is a long time so it isn’t out of the question
Ok back to hardware, it’s getting interesting again

  • Think laptops sill become peripherals to our phones. [interesting concept, Mac is already on the way] Like a monitor and keyboard for the same environment other phone, but with more processing power.
  • Data analytics will be more important. More parallelization and more devices yields more crosstalk and more data to sift through
  • Cloud will take care of non functional requirements
  • Apps are going to be about code, dependencies and binding rather than a self contained unit. The shared modular environment will handle the rest

future known facts

  • JEE 8 is going to attempt a modular programming environment [how does this make it less complex?]
