openjdk vs oracle's jdk

[Alok Singh Mahor]

Hi all

I guess most of the Linux distributions distribute openjdk. I also use openjdk primarily. but there are situations sometimes where oracle/sun's jdk is recommended. like these days I am working on Hadoop/Hbase.

I am little reluctant to switch to oracle jdk.

would anyone tell me what is drawback of openjdk? openjdk is old enough still things are written on top of sun's jdk.

I see openjdk will be adopted in future, Am I wrong if I think so?

or if there is very little difference between these two then should I be flexible to choose between these two according to situation?

thanks

apart from the political reasons of Free vs Non Free and reasons like the recent vulnerabilities , i see some ray of hope with http://www.infoworld.com/t/java-programming/red-hats-java-leadership-grows-oracles-wanes-214137 , for all practical purposes i go by the rule of thumb use what works , if its working do not try to change .

Most distributions carry both openjdk, oracle jdk and several other implementations. Unless that has changed in recent ones.

Both are equally capable platforms like Satya pointed out and whatever works for you is great.

I have not seen any comprehensive example of code written specifically for Sun JDK. Although one could write Sun JDK specific code, most specific code can be converted to platform agnostic by using Apache Commons library. Open JDK "is" open source version of Sun JDK. Sun JDK contains extra proprietary libraries. Oracle also may have and is capable of introducing optimizations which may or may not be available in Open JDK. Having said that, I have not found Open JDK any less capable.

I think you will be looking at both versions being available side by side for very long time.

I would suggest just choose one and stick with it for lack of surprises.

 

thanks
