junit4 behavior change
by Orion Poplawski
Running apache-poi tests on Fedora 13 with junit4 4.6 I get:
[junit] Running org.apache.poi.hssf.usermodel.TestBugs
[junit] Warning, header block comes after data blocks in POIFS block listing
[junit] Warning, incorrectly terminated empty data blocks in POIFS block
listing (should end
at -2, ended at 0)
[junit] Tests run: 91, Failures: 0, Errors: 0, Time elapsed: 5.654 sec
On rawhide with junit4 4.8.2 I get:
[junit] Running org.apache.poi.hssf.usermodel.TestBugs
[junit] Warning, header block comes after data blocks in POIFS block listing
[junit] Warning, incorrectly terminated empty data blocks in POIFS block
listing (should end at -2, ended at 0)
[junit] Tests run: 91, Failures: 0, Errors: 1, Time elapsed: 13.797 sec
BUILD FAILED
/builddir/build/BUILD/poi-3.6/build.xml:563: Tests failed
These warnings are written with System.err.println(). Does junit4 now
automatically record an error if something is written to stderr?

JUnit4 being obsoleted by JUnit
by Stanislav Ochotnicky
Recent versions of JUnit4 have backward compatible layer that is able to
emulate JUnit versions 3.x.x. We currently have 4.8.2 in rawhide thanks to
Alexander Kurtakov.
I have done some testing of this backward compatibility and I was able
to successfully replace junit with recent junit4 and build packages:
* jakarta-commons-logging
* jakarta-commons-io
* jakarta-commons-dbcp
* eclipse (unmodified spec, but replaced junit.jar symlink in
/usr/share/java with junit4.jar)
This means we can begin phasing out separate junit4 package and
basically overwrite junit package with it. This will be done probably
in the next few days. New version of junit will of course offer backward
compatible symlinks, so no modifications to your packages should be
necessary. Problems might occur anyway, so take this as a heads-up.
junit package in devel is currently orpahned and I plan to take it and
do these changes, unless anyone has conflicting ideas. Other ideas are
welcome too of course.

Doesn't work, because the build itself needs ant which doesn't run with Sun JDK5. Unless I manually
install another ant and force it to the path.

Looks like that gij doesn't use xerces to provide jaxp services:
# alternatives --display jaxp_parser_impl
jaxp_parser_impl - status is manual.
link currently points to /usr/share/java/xerces-j2.jar
/usr/share/java/libgcj-4.4.4.jar - priority 20
/usr/share/java/xerces-j2.jar - priority 40
Current `best' version is /usr/share/java/xerces-j2.jar.
But running ant with gij and gcj yelds:
-------------------------------------------
XML Parser information
-------------------------------------------
XML Parser : org.apache.xerces.jaxp.SAXParserImpl
XML Parser Location: /usr/share/java/jaxp_parser_impl.jar
Namespace-aware parser : org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser
Namespace-aware parser Location: /usr/share/java/jaxp_parser_impl.jar
Maybe gij finds it's own jaxp implementation in libgcj.jar before trying xerves, and so ant works.
But I don't like the idea of making whatever jaxp parser comes in libgcj be the system-wide default
for JDK 5. Or maybe gij and classpath provide for some JDK6 features, including the class file
format.

Re: [fedora-java] ant with jdk5
by Fernando Lozano
Hi there,
I filled Bug 601830 about this problem we were discussing on the users list. So far it looks like
xerces-j2 was built for Fedora-13 using OpenJDK6 but without a target directive, and thus requires
Java >= 1.6.0. This prevents me from running Apache Ant using Sun JDK 5 (repackaged by JPackage
standards).
I hope the mantainer decides this is worth to fix and release a new xerces-j2 package compatible
with at least Java 1.5.0. In the mean time:
- What is class data version 45.3 (from log4j.jar)?
- How to install (from Fedora or JPackage repos) an jaxp_parser_impl.jar / Xerces J2 complied for
JDK 5m if there is such a thing?
- If there isn't, where should I change the SPEC from xervers-j2*src.rpm to rebuild it using Sun
JDK5 or to add target=1.5.0?
- How can it be that ant runs fine using gij which in theory supports only Java 5, but not with Sun
JDK 5?

Howto for Java on Fedora
by Paul Michael Reilly
I've been running Sun Java on my Fedora systems for years and years now.
Having just installed F13, I figured I'd see how the yum induced Java
experience is lately. So I blithely yum installed Ant and ran "ant
-version" only to discover the classpath is not nice. So I figured I'd
google the Fedora Java howto documentation after discovering there is
next to nothing in /usr/share/doc/ant-1.7.1 that is Fedora specific.
But no such documents exist. Or at least my simple minded queries are
not turning up anything along the lines of: "Here's what you want to do
to set up a decent Java programming experience in recent Fedora releases
(say, f10 on up)" True, there is a fedoraproject.org wiki page on
JavaFAQ but that seems very stale (f9 based) and there is a fedoraunity
project that has some material on Fedora/Java, but no sites that I would
characterize as authoritative or definitive.
Is anyone paying attention to this list aware of "good" Java/Fedora
documentation? Is there interest (other than mine) in seeing Fedora be
used as a first class Java development platform? If there is, in fact,
an opportunity to fill this gap, would the fedoraproject.org wiki be the
place to put something? Someplace else?
Thanks,

PTP review
by Orion Poplawski
I'm looking for someone to review the eclipse-ptp package:
https://bugzilla.redhat.com/show_bug.cgi?id=529278
Description:
The aim of the parallel tools platform project is to produce an open-source
industry-strength platform that provides a highly integrated environment
specifically designed for parallel application development. The project will
provide:
- a standard, portable parallel IDE that supports a wide range of parallel
architectures and runtime systems
- a scalable parallel debugger
- support for the integration of a wide range of parallel tools
- an environment that simplifies the end-user interaction with parallel
systems
The photran project (which is already in Fedora and I maintain) merged with
PTP and so this package replaces that. It's a big package, I'm afraid, but I
hope it's mostly all set.
