> issue.  Java as part of the installation system, also enterprise apps 
> which require a particular JVM, also small to medium apps which work

> not many resources.  But, if we don't engage now, it could be painful 
> later.  On JCK: any JVM can be certified by sending a request to Sun. 
> Two major stipulations: must be predominantly based on OpenJDK (which 
> most are), and you can't say "94% compliant": compliant or not.  This 
> should be sufficient to certify a completely open source JDK.  Ted: can 
> you send us the link?  Joseph: should be prominent on OpenJDK site, will

> as needed w/o hassle?  Joseph: yes.  Java only; JDK 7 will include newer 
> stuff, like Java Web Start.  Can't speak for the distros or other JVMs, 
> but there should be no roadblocks for 100% certified, open source Java 
> this calendar year.  Still concerns; standard needs two implementations. 
>   Dan: Sun's strategy to closed test suite?  Joseph: closed, available 
> but not free, more of a tracking thing from Sun's perspective, tied to 
> OpenJDK.  Ted: JCK license will be "free as in beer", can only use it to 
> test an implementation derived from OpenJDK?  Joseph: key is what "based 
> on" means.  100% black-box implementation wouldn't probably work, but 
> Sun intends to be rather liberal.  Could possibly do it now, but the 
> rules are still unclear.  Jeff: good long-term LSB strategy then would 
> be to require a Sun-compliant Java in distros, using this certification 
> strategy?  Joseph: yes.  Ted: not specify the policy, just the result. 
> Russ: right now, there are two alternatives for Java: closed-source with 
> indemnification (not suitable) and open-source (not complete).  So, no 
> current solution for CentOS.  Jeff: right, this is a long-term strategy. 
>   Ted: timeline?  Joseph: goal is to get OpenJDK into Ubuntu main.  Ted:

> service pack/update level.  Ted: may also depend on who you talk to; 
> overcautious.  Would be nice to allow certification to the abstract LSB 
> platform.  Joseph: question of trust.  How much would Sun trust the LSB 
> to be stable enough?  SunOS/Solaris ABI compliance wasn't even 100% 
> (discrepancy on page size assumptions).  Joseph is not qualified to give 
> an answer.  Ted: could require more effort and conversation to make that 
> happen.  Joseph: can't hold "LSB" in your hand; can hold RHEL 5 or SLES 
> 10.  Ted: we are expanding our tests.  Can also happen at the app level. 
>   Jeff: question is, can we meet the confidence level Sun would require? 
>   Joseph: do we need it?  Distro tests their JDK; LSB accepts that. 
> Maybe we don't need anything more than that.  Jeff: what about apps that

> specific IBM JVM; Ted runs it on Debian, on which the IBM JVM is not 
> certified.  Users are doing that unsupported; can we make that better? 
> Joseph: how to handle multiple JVMs on a single box?  Ted: each app 
> comes with its own bundled JVM.  Joseph: then the Java certification is 
> irrelevant; the whole app (including the JVM) becomes a LSB issue as-is. 
>   Ted: yes, correct; we'd like to make that possible.  Make it possible. 
>   Robert: is a short-term goal, we're close, will Sun certify?  Ted: two 
> problems--will the rules allow it, and will the JVM vendors do it? 
> Robert: question is, will Sun be willing?  What effort will Sun put into 
> it?  Joseph: common case is that the distro ships a trustworthy JRE.  If 
> the JRE is bundled, the app can do its own LSB certification.  Java cert 
> is irrelevant.  Believes that it is a desireable attribute for a JVM to 
> be LSB-compliant, because it will make the ISV's life easier.  Jeff: can 
> such an app be called a "Java app"?  Joseph: isn't it just "Lotus Notes"
