OpenJDK 6: Some more regression test results for b11

To address a configuration issue with the previously reported regression tests results for OpenJDK 6 b11, I reran the jdk tests with the display set to a virtual framebuffer and 77 more tests pass. In summary now:

• JDK, 2,989 tests pass, 32 tests fail, 22 tests have errors.

Note that the jtdiff command, included as part of jtreg, can be used to compare the output of different regression test runs.

OpenJDK 6: Some regression test results for b11

For comparison purposes, I've uploaded the results of the automated regression tests (-a option to jtreg) from the OpenJDK 6 build 11 source bundle run against a Sun-internal Linux build:

• HotSpot, 5 tests pass.

• Langtools, 1,349 tests pass, 2 tests fail, 6 tests have errors.

• JDK, 2,912 tests pass, 109 tests fail, 22 tests have errors.

I ran the tests remotely and didn't set a usable display so about 72 of the JDK failures are from the AWT tests not having a display; I'll rerun the affected tests and verify they will pass as expected. At least one of the langtools failures seems to be from an overly zealous version check that should be modified.

I've also ran tests on a Solaris SPARC system; the HotSpot and langtools results were identical and there were a few differences in the JDK results.

OpenJDK 6: Sources for b11 published

On July 15, the OpenJDK 6 b11 source bundle was published.

This source bundle includes:

• All the relevant JDK security fixes that recently went out. More information about these changes is available from the Sun Alerts linked to from one of Sun's security pages. Some of the security fixes only affect closed code or areas otherwise not open sourced as part of OpenJDK 6 so not all the security fixes are reflected in the source bundle.

• Ports of existing fixes in various areas. In HotSpot, fixes from previous 6 update releases (6497639, 6623167, 6623167, 6497639, 6599425), a build issue (6681796), and a fix for an Eclipse crash (6614100). In the libraries, there were fixes for graphics (6691328, 6608764, 6624717) and monitoring (6685178).

• Changes to address various of the previously raised concerns on licensing/copyright and binary artifacts. First, I applied Andrew John Hughes's fix to remove jscheme.jar (6695776). Next, Kelly and Iris have fixed many other licensing and binary artifact issues (6565364, 6705945, 6601384, 6601377, 6713083, 6695777 6710791).

• Miscellaneous other fixes cleaning up regression tests (6621691, 6596323, 6710579) and other matters (6717575, 6665028, 6589868).

I'm in the process of updating the Gervill sound engine in OpenJDK 6 to the current version; that work will be complete by build 12. In the meantime, as an initial step the spacing of the source code has been normalized (6717694).

I'd expect b12 to be available within two weeks; besides the Gervill work, a few more licensing/artifact fixes may be included too. Going forward, I plan to get the OpenJDK 6 sources into a public Mercurial repository by the end of the summer; that will allow fixes put there to be shared more quickly and should also allow more work to go on directly in the upstream code base.

OpenJDK 6: Congratulations to IcedTea and Red Hat

Congratulations to the IcedTea project and Red Hat for producing an OpenJDK binary in Fedora 9 that passes the Java SE TCK!

We'll continue working on getting the remaining fixes needed to achieve this incorporated directly into OpenJDK 6 too.

OpenJDK 6: Sources for b10 published

On May 30, the OpenJDK 6 b10 source bundle was published. Notable fixes in this build include:

• Clarifications and corrections to the build instructions (6644659, 6682167, 6563616, 6611685, 6597857)

• Fixes related to building cryptography (6683078, 6644659)

• 2D bug fixes (6604044, 6636469), including a fix from Andrew Haley and Keith Seitz of Red Hat to correct color management related regression and JCK failures (6523403).

• Replacing the encumbered sound engine with Gervill (6702956)

• Updating time zone data to 2008c (6707643)

• Collections fixes (6691185, 6691215)

• Start of addressing the copyright/licensing concerns raised by Debian (6695553, 6703931)

• Deleting or modifying regression tests to be more appropriate for OpenJDK (6673853, 6602426, 6704655, 6705893)

With the removal of the binary plug for sound, the only remaining plug in OpenJDK 6 is for SNMP support. Work continues to address the remaining copyright and licensing concerns in the code base. Some regression tests, such as those in networking and javax.script, should probably be modified to more easily accept configuration options without having to modify the source of the tests; discussion on how best to do that has started.

OpenJDK: jtreg and regression tests

Huzzah! Through the dedicated efforts of Jon and others, jtreg is now open sourced! The jtreg program is the test harness used to run the regression tests that come with the JDK sources.

The JCK tests verify properties that should be true of all implementations of a given Java SE specification. The JDK regression tests are different; while many of them test properties that should be true of all implementations, some regression tests look at properties we want to be true of our JDK implementation but are not strictly required by the specification. Therefore, while a failing regression test most likely indicates a problem, in some cases the failure may not be a correctness issue per se. This situation is certainly feasible with ports of the JDK to operating systems sufficiently different than windows, Solaris, and Linux; shell tests are especially susceptible to those OS differences. Creating new shell tests should be avoided if possible and the porting effort may include updating regression tests to make them aware of the new platform.

OpenJDK 6: Sources for b09 published

On April 11, the OpenJDK 6 b09 source bundle was published.

Notable fixes in this build include:

• Linux printing issues (6633656, 6678161)

• a correction to the JAX-WS 2.0 → 2.1 upgrade (6672868)

• Time zone updates (6650748, 6679340)

This will very likely be the last source drop until after JavaOne.

OpenJDK 6: Sources for b07 and b08 published

The sources for OpenJDK 6 b07 were posted on March 20 followed by b08 on March 27.

The most notable fixes in b07 were:

• Resolving the last remaining JCK signature test failure (6636951); other JCK failures remain.

• Making window decorations appear (6586752).

• Updating to the 1.1 version of the OpenJDK™ trademark notification.

• Enabling the out-of-the-box build to succeed without any binary plugs being present (6672710). If the plugs aren't used, neither the midi synthesizer nor SNMP will work at runtime.

After b07, Red Hat reported that the source bundle contained some suspect binary artifacts. In b08, we addressed all the make and src artifacts and some of the test ones (6679994). We're reviewing how to make the licensing of the remaining non-source files in the bundle clearer. Additionally, a separate build problem was addressed (6613927)

At present, there is not a particular time line for the next code drop. The fixes in the next drop will include time zone updates (6650748, 6679340).

OpenJDK 6 and Distros

There are now OpenJDK 6 packages for the upcoming Hardy Heron Unbuntu Universe and Lilian has announced that OpenJDK 6 will be a part of Fedora 9.

OpenJDK 6: Sources for b06 Published

The second code drop for OpenJDK 6, b06, was published earlier today, February 29, 2008, at the usual location.

This drop has several changes of note:

• As previous announced, Phil Race has moved the imaging classes from closed to open, reducing the need for the binary plugs (6662775 Move Imaging and color classes from closed to open).

• Rama upgraded the version of JAX-WS in OpenJDK 6 from 2.0 to 2.1 (6605798 JAX-WS RI 2.1.1 should be integrated in OpenJDK6). As an endorsed standard, the version of JAX-WS shipped in a JDK can be upgraded; the JAX-WS 2.0 → 2.1 upgrade was also done in Sun's JDK 6 update 4.)

• The JMX team modified the build so that the SNMP portion of the build will not fail if the binary plug isn't present, with the caveat that without the plug SNMP won't work at runtime (6661448 Make the SNMP agent optional when OPENJDK=true and IMPORT_BINARY_PLUGS=false).

• Various l10n and i18n issues were addressed (including 6573250 Java.util.Currency.getSymbol(Locale) returns wrong value when locale is not US

• The most recent time zone information is now being used (6646197 (tz) Support tzdata2007k).

• Also of note is the inclusion of a trademark notification for "OpenJDK" in the TRADEMARK file in the top-level directory of the source bundle.

I expect with next drop will be available within two weeks, by March 14, 2008.
