Apache Harmony for Apache internal use?
Hi Infrastructure team.
I'm a Harmony developer and wondering what's necessary for
Apache to use it's own Harmony for internal use rather than Sun's or
another Java.
For example can we (in some future) host JIRA on top of Harmony?
What would be criteria for that (like Harmony is able to run it for XX
days or something else)?
Are there other areas where ASF currently
uses Sun's or another Java and we could use Harmony instead?
Thanks,
Mikhail

It would be good idea to take some of these as scenarios for oncoming
milestones.

Interesting idea. Can we get the software to run with Harmony so that
we have enough confidence? For example, before the infra people tell
us how many hours are considered acceptable, it's probably better for
us to tell the infra people how many hours Harmony can run with the
software smoothly, and some performance number is necessary as well.
Can we (or some other Apache people) talk to Atlassian directly about
the software? Or as an alternative as Alexei suggested, we can try to
get a trial JIRA setup with Harmony separately. Once we have a good
confidence level, we can try to use this Harmony-based JIRA for
Harmony project at first, then we ask for more infra diffusion.

I have strong +1 for this type of activity. IMO it is very hard to
persuade people to use Harmony for their projects if Apache by itself
doesn't trust it. As a first step we may ask to create a separate
Harmony-powered instance of JIRA, solely for Harmony purposes.
BTW, some Apache projects (Geronimo for example) use Confluence Wiki
that is also a J2EE product from Atlassian [1]. We may try to run it
on Harmony too.

Hi Henri,

Yes, I've created a separate JIRA issue for this. I put there the
detailed instruction on what it needs to be done to run JIRA on top of
Harmony. Please see [1]. The archive with stubs is also attached
there.
Harmony community is really interested in all kind of results you may
get by using JIRA+Harmony on real workloads. BTW if you like Harmony
community members to receive your messages you should probably
subscribe to dev@harmony.apache.org first since only subscribers'
messages are visible to others.

Cool. Go and grab the latest Harmony milestone from our downloads page
[1]. Sounds like you will need to patch JIRA to satisfy it's dependency
on Sun internals [2].
You know where to come for assistance. Please report back, good or bad.

Thanks folks for your prompt and valuable comments and info!
A good news IMHO is there is no allergy to moving this direction,
so we can now set stability and performance targets for ourselves
and return to you when we think we are ready

Continuum and/or Gump builds both leap to mind as good candidates for
testing Harmony.

The only comments are:
We need to ensure that none of our code depends on sun.* packages.
See: http://java.sun.com/products/jdk/faq/faq-sun-packages.html
Currently the com.atlassian.velocity.VelocityHelper is the only
class that has been identified to use a sun.* class.
and
Please note that the class is actually in atlassian-velocity and
not JIRA.
The issue has been open since June 2007.

Hi all,
FYI today I've download evaluation version of JIRA and tried to run it
with the most recent version of our HDK. At the beginning it didn't
want to work due to NoClassDefFound error for following classes:
com/sun/image/codec/jpeg/ImageFormatException.class
sun/security/action/GetPropertyAction.class
Then I created simple stubs for them and placed to
$CATALINA_HOME/shared/classes. Then I run tomcat again and ... JIRA
started to work. Without any exceptions, stacktraces, hangs and
crashes! I was playing with it about two hours. I've successfully
created a new project, project's components, several users and
permissions for them. First two JIRA issues were successfully filed.
Here is a screenshot to prove that this wasn't a figment of my
imagination - [1] . Don't pay attention to JVM vendor. Most likely
it's value is mistakenly taken from "java.specification.vendor" or
"java.vm.specification.vendor".
Of course I understand this wasn't a stress test in a production
environment. But the fact that Harmony already is able to host (small)
JIRA instances deserves community attention IMO.

One good option for testing harmony might be to try the Derby functional
tests. The Derby tests traditionally are very good at finding jvm bugs,
especially JIT bugs.

At the same time having some live examples of Harmony viability IMO
can also be rather important. At least for that group of
users/customers who don't believe in words and need more motivation
to start spending their time/resource on downloading and trying 50M
snapshot. In other words, I don't see any harm in the fact that
Harmony will "run a busy copy of JIRA". Especially in case if it is
already able to do this.

Me too! Please download a copy of Harmony [1] and try running a Java
application on it. If it works, let us know (a bit of developer
stroking always helps <g>) but more importantly if it doesn't work also
let us know. The people who frequent this list are incredibly motivated
to fix problems in real applications -- all you need to inspire them is
a good bug report.

Yep.

The last set of results that I'm aware of for Derby on Harmony was
uploaded by Sean in HARMONY-4726 and published here [1].
Note that this was on Derby 10.3.1.4, and apparently Harmony as it was
back in March 2007 (r522033)?
Sean: Is that right? The issue was raised in September. Were you really
using such an old VM?

In fact, Harmony uses the Eclipse compiler for Java [1] so it already
compiles all Java code thanks to our friends in Eclipse.
We have a flexible test framework that allows us to plug-in
applications' test suites, and we are expanding that to demonstrate
Harmony's ability to run lots of different Java applications.
