Re: [ljc] Java 6 to 7 Auto Upgrade

Hey Martijn,

I got the information that Oracle won't be keeping OpenJDK as up to date as Oracle JDK from various discussions about the issue on the internet. For example, there is this topic on Stack Overflow:

http://stackoverflow.com/questions/8562293/where-are-the-java-7-updates-for-openjdk

Where the (current) first answer says this which sums up some of my problems with Oracle's way of doing things here:

"We now have a combination of things that are making usage of Java really painful in open source server deployment

  • Oracle JDK has updates (including security fixes) that no OpenJDK package has. This makes using anything other than Oracle JDK result in poorer security
  • Oracle JDK can no longer be packaged distributed by third parties (e.g. Ubuntu). Now we have to install it by hand or script it, and maintain it, on all our serve"
There doesn't appear to be clarity regarding the flow of bug and security fixes into the Open JDK vs Oracle JDK.

I'm not sure where you heard that from? OpenJDK is the RI for Java 7+,
so Oracle (as part of the OpenJDK community) will fix issues there,
which then go into their supported binary. The 2 exceptions to this
are:

* I'm not 100% sure on their security fix policy.  My understanding is
that they do go into the OpenJDK, but I'm not sure which way the fixes
flow.

* The proprietary part of Oracle's binary (IIRC Webstart + something
else) will only be fixed there.

Cheers,
Martijn
