OpenJDK 6: Some regression test results for b13

For regression testing of OpenJDK 6, the big news in b13 is due to work by Jon on multiple fronts; by getting out a new version of jtreg and developing a number of test fixes, all the langtools regression tests now pass when run in "samevm" mode (jtreg -s ...). As the name implies, in same vm mode a test is run in the same jvm as the previous test as opposed to starting a fresh jvm for each test, giving much speedier test results.

The base jtreg flags for these test runs were -a -ignore:quiet with -s just used for the langtools tests. On a per workspace basis, the results on Linux for OpenJDK 6 build 13 are:

• HotSpot, 5 tests pass.

• Langtools, 1,351 tests pass.

• JDK, 3,072 test pass, 23 tests fail, 3 tests have errors.

Compared to the regression test results for b12, in b13 HotSpot is unchanged:

0: ./b12-hotspot/summary.txt  pass: 5
1: ./b13-hotspot/summary.txt  pass: 5

No differences

The langtools tests now all pass:

0: ./b12-langtools/summary.txt  pass: 1,346; fail: 2
1: ./b13-langtools/summary.txt  pass: 1,351

And in jdk, several dozen new tests were added and some previously failing tests pass:

1: ./b13-jdk/summary.txt  pass: 3,072; fail: 23; error: 3

OpenJDK 6: Sources for b13 published

On November 7, the OpenJDK 6 b13 source bundle was published. Changes of note in this build:

• In the langtools area, besides a few miscellaneous bug fixes (6760834, 6725036, 6657499), all the langtools regression tests now pass out of the box (6728697, 6707027) and if using the most recent version of jtreg, the langtools regression tests can be run in the much faster "same vm" mode of jtreg, enabled with the -s option (6749967, 6748541, 6748546, 6748601, 6759775, 6759795, 6759796, 6759996, 6760805, 6760930).

• Gervill update, including applying a patch from IcedTea (6758986, 6748247, 6748251).

• Publishing a few dozen additional existing regression tests as open source (6601457, 6759433, 6740185).

• JMX and monitoring fixes (6651382, 6616825, 6756202, 6754672).

• Man page updates (6757036, 6392810, 6504867, 6326773).

• Assorted other fixes (6746055, 6621697, 6756569, 6356642, 6761678).

Kelly has made good progress on the Mercurial repository, but some more work remain to be done. I'd expect to have trial repositories available within a week or two.

OpenJDK 6 Genealogy

To address some of the questions that have come up recently in comments and elsewhere, I've prepared a diagram of OpenJDK 6's genealogy:

The original JDK 6 code base begat two lines of heirs: JDK 7 and the sequence of 6 update releases. The decision to open source the JDK code base came late in the life cycle of the development of JDK 6 so a build of JDK 7 was the first be published as open source. By the time JDK 7 was published as OpenJDK 7, the first post-GA update to JDK 6, 6u1, had already shipped. Work continued in both the OpenJDK 7 and 6 update trains. However, an open source implementation of the Java SE 6 specification was needed as well. After considering the alternatives, OpenJDK 7 build 20 was chosen as the basis of a backward branch to create OpenJDK 6 by removing changes inappropriate for a Java SE 6 implementation. Since then, all three trains, 6 update, OpenJDK 7, and OpenJDK 6, have continued evolving, with certain fixes being ported between the releases.

At some point in the future, the OpenJDK 7 code base will in turn presumably give rise to OpenJDK 7 update releases and OpenJDK 8.

OpenJDK 6 and 6u10 features

There have been a number of inquiries about when the various new features of 6u10 would be available in OpenJDK.

OpenJDK 6 build 12 contained ports of bug fixes from a number of 6u10 component areas (corba, jaxp, jaxws, langtools). Most changes from the core jdk component area of 6u10 were not ported. The porting effort that took place of a relatively small number of bugs to a subset of the full OpenJDK code base was still a sizeable effort. The full set of changes made to the core jdk in 6u10 is many times larger with a proportionally larger porting cost. We at Sun do not plan to do a wholesale port of those 6u10 features from the core jdk to OpenJDK 6. However, over the coming months we will be porting those 6u10 features to OpenJDK 7 and we would welcome community assistance in backporting appropriate features from OpenJDK 7 to OpenJDK 6. (These jdk area features in 6u10 are separate from plugin and webstart functionality.)
