glibj-generics-latest.zip on builder old?

On http://builder.classpath.org/dist/, glibj-generics-latest.zip is
dated Oct 18th as opposed to all the other files including
classpath-generics-latest.tar.gz and glibj-latest.zip which are dated
Oct 31st as expected. Is something up with the generics build causing
it to fail to produce an updated zip?

This is why Andrew's hard work with the generics merge the other day
didn't result in a wonderfully huge Japi diff email...

Thanks,
Stuart.

Yes, according to classpath-testresults starting Oct 18th we have:
http://article.gmane.org/gmane.comp.java.classpath.testresults/2667

6267 problems (1 error, 6266 warnings)make[1]: *** [compile-classes]
Error 255
make[1]: Leaving directory `/home/cpdev/Nightly/generics/build/lib'
make: *** [all-recursive] Error 1

Unfortunately the large number of warnings obscure the 1 error.

Looking through the log it is:
1729. ERROR in ../../classpath/java/util/EnumSet.java (at line 252)
        return copyOf((EnumSet<T>) other);
               ^^^^^^
The method copyOf(EnumSet<T>) is ambiguous for the type EnumSet<T>

Sometimes huge japi diff emails are also caught by mailman as "way too
big an improve to be true" :)

So do we reckon this is a Classpath bug or an ecj issue? Andrew,
presumably -generics builds for you - how does your ecj version
compare to the one on builder?

Stuart.

PS I know, I'm being a pain in the neck, I'm just impatient to see the
Japi results with that latest merge in ;) Sorry

This seems to have been fixed now. Although I am not sure how that
happened precisely. The ecj version used on builder is: Eclipse Java
Compiler 0.722, 3.3.0 milestone-3

OK, sorry, my mistake. I wasn't looking at the right log file. It seems
to be broken for current ecj CVS. So I made builder use the installed
ecj for now (v_585_R31x, 3.1.2 release) and now it compiles also on
builder again.

If it really is a bug in the ecj (org.eclipse.jdt.core) CVS version then
we should create a bug report. Could someone familiar with EnumSet take
a look?

Thanks,

Afaik the Harmony people had a similar bug with ecj and reported this.

But that is good code isn't it?
Or is there a reason the compiler refuses it?

I upgraded the ecj on builder to v_677_R32x, 3.2.1
(ecj-bootstrap-gcj_3.2.1-3_i386.deb)

Part of the issue is Japitools aborting entirely part way through
Japizing when certain kinds of corrupt class files are encountered.

Work on fixing this is in progress.

Ah, that would explain why whole packages were disappearing from the
comparison. Thanks for working on Japitools. I wish more projects would
use it when they do new releases to get a good overview of compatibility
between releases.

Do the zip files as published at http://builder.classpath.org/dist/ work
correct for Japitools now?

Yes, this is great news.  I believe it calls for a free java developer
gathering like the one in Oldenburg a long time ago.  This time with
people from SUN as well as all the developers from the Classpath
project cluster. :)

Any volunteer to make it happen.  I know a gathering is planned for
FOSDEM, perhaps it could be extended and some travel sponsoring can be
organized for it?

Yes that makes sense. We got confirmation from the Fosdem organizers
that for FOSDEM 2007 (24-25th February in Brussels, Belgium) we will
have a room for 100 people and Sun.be has asked for an OpenJDK booth
that the FOSDEM organization will place not too far away from that room.

We have some friends at Sun now that would like to join us for Fosdem.
Normally we have three "themes" for our Fosdem meeting (Sat afternoon,
Sun morning, Sun afternoon). For this year it is probably a good idea to
make those:

- GNU Classpath & friends - Reflection & Future (Party!)
- OpenJDK - Welcome to/from the community
- GNU/Linux distro packaging for the new libre Java world

Normally our Fosdem meeting is completely volunteer based and people
come without any sponsorship. Just because it is such a hassle to make
someone responsible for managing and tracking money. But if you would
like to help with sponsorship and coordination that would be very nice.

I've spoken with Andreas Schuldei (stockholm on IRC) in Debian, and he
is interested in helping out.  We need a list of interested people
with and without sponsoring needs, and someone to pick the ones
deserving to get their travel sponsored.

We have discussed it on #debian-java a bit, and will continue to do
so.  <URL:http://wiki.debian.org/Java/DevJam> is a good starting
place.

I suggest Mark get to pick the three people to join him in the group
to select who to sponsor.  Fine with this, Mark?

I know there were intentions to hold the next devjam in America
somewhere, but suggest we grab the chance to gather at FOSDEM and try
later to organize something in Canada or Mexico.  I assume the current

Following up to this:

I've had a conversation with the organizers, and apparently this is
not an attempt to replace the usual Classpath get-together, but a
renaming.  There will be a Classpath meeting, as usual, and you won't
have to decide to go to the DevJam instead.

Yes. Sorry if that was not clear. Since we wanted to have three sessions
at Fosdem and had already decided those would be about GNU Classpath &
Friends, OpenJDK and GNU/Linux distro Packaging it made sense to
officially turn this into a shared meeting. As
http://wiki.debian.org/Java/DevJam/2007/Fosdem says:

        We are organizing a meeting which is a merger of two events and
        what we hope will be the start of a close collaboration of the
        free software community with the new Sun OpenJDK project.

Yes, my involvent in the FOSDEM java gathering and the reason I am
calling for a devjam at the same time and location is to increase the
chance of having the people working on free java present and talking
to each other.  Please see it as a friendly reenforcement of the
Classpath meeting, and not as a hostile takeover.

At the moment 21 people have signed up on thewiki page and thus
expressed their interest in joining.  7 of these seem to be interested
in sponsoring, at least for the travel.  I have no idea what it would
cost to get them there, but the numbers on the page indicate values
around 250 EURO, so I guestimate 7 * 300 EURO = 2100 EURO.  That is
not to bad, and should be possible to collect.  I hope we get at least
that amount of sponsoring.  No idea how much accomidation will cost,
but I'm sure it will be some extra expences. :)

Andreas, how are you doing with collecting sponsoring?  How much money
do Debian have left in the "Java pile" left over from last devjam?

I'm not sure I can make it myself, but hope the rest of you will have
a productive meeting even if I have to stay home. :)
