Poll Reveals Diversity of Opinions on JDK 7

Posted by editor on July 31, 2009 at 8:58 AM PDT

This past week's java.net poll about the emerging JDK 7 drew 488 votes and almost 2000 words of commentary and debate by the voters (in 16 comments). The specific poll question and results were:

What's your view of the emerging JDK 7?

  • 10.4% (51 votes) - It's a major step forward
  • 30.3% (148 votes) - It includes some important features
  • 16.3% (80 votes) - It's a typical JDK release
  • 41.5% (203 votes) - The most significant problems are not addressed
  • 1.2% (6 votes) - Other

Summing the results for the first two responses tells us that just under 41% of the voting expressed a positive point of view toward JDK 7. The poll participants were thus fairly evenly divided with respect to having a positive or negative view of JDK 7, while 16% consider the upcoming JDK 7 release to be "typical".

The comments span the gamut, from endlesslove's sarcastic

I wonder what's so hard in fixing that RFE [bug 6530906]. Maybe in the year 2025, that RFE will graduate from its state of being "accepted"?

to arooaroo's

JDK doesn't seem a massive step forward. I'm pleased to see the nio2 improvements though.

to massimoh's "Jigsaw is big" comment, which states, in part:

My biggest concern is that Jigsaw is done right and delivers an elegant solution to the issues. If they do that, then JDK7 will be a major evolution.

and dutchiedave's

I really don't understand the issue people have with bloat. The number of people that are negatively effected by the size of the JVM is very small. Whether the JVM is 10MB or 15MB really makes no difference to the majority of java clients. Useful features should be implemented in a timel manner and 'bloat' should not be used as a reason not to implement them.

A very big discussion (12 comments) was instigated by cowwoc's brief comment "Reified Generics Please":

Generics through erasure was a major eyesore introduced in Java5. Please improve readability by fixing Generics in Java7!

linuxhippy initiated the "bloat" discussion that dutchiedave responded to, by aiming this at cowwoc:

@cowwoc: The current generics can't be simply removed, so they will stay. Can you imagine what another (second!) generic implementation would do to the Java language. To be honest I am against bloating the language any further, and try to concentrate on a next-generation Java successor like scala.

Which, not unexpectedly, launched a discussion about Scala. scotty69 challenged the assumption that you can "just use Scala" as the solution to Java inadequacies:

Please help me: I have - say - 200.000+ lines of 3 years old Java code, mature, thoroughly tested, battle proof. My customer wants me to add feature X with about 2.000 lines of new code and and 3.000 lines of existing code to be changed, tight budget as usual. Do your really think that it's a good idea to to introduce Scala in this scenario to "extend Java classes, call methods and so on"? Do you have experience in mixing a large legacy Java codebase with new Scala elements? Can you tell me how the tool-chain could look like?

Which brought a very lengthy response from aehrenr, which brought another response from scotty69, ... See the poll results page for the full discussion.

New poll: Project Kenai

This week's new java.net poll asks What do you think about Project Kenai? Project Kenai is Sun's new "onramp for the developer cloud experience of tomorrow, where you can host your open source projects and code, as well as find and collaborate with developers of like mind." Voting will be open through next Thursday.

Carol McDonald writes about JPA 2.0 Concurrency and locking: "JPA 2.0 Concurrency: Optimistic and Pessimistic locking, how, why, advantages, disadvantages: Optimistic locking lets concurrent transactions process simultaneously, but detects and prevent collisions, this works best for applications where most concurrent transactions do not conflict.
