Running with the usual jtreg flags, "-a -ignore:quiet" in all repositories and adding "-s -ea -esa" for langtools, the basic regression test results on Linux forOpenJDK 6 build 20 are:
  • HotSpot, 85 tests passed.
  • Langtools, 1,365 tests passed.

    JDK, 3,273 tests pass, 33 fail, and 2 have errors.
All the HotSpot tests continue to pass and more tests were added:

In langtools all the tests continue to pass and a few tests were added:

And in jdk a few tests were also added by virtue of the backports. Otherwise, the existing tests have generally consistent results.As done starting with build 18, the test run below was executed outside of Sun's and Oracle's wide-area network using generally accessible hosts for the network configuration file; to specify the networking configuratuion file, pass a "-e JTREG_TESTENV=Path_to_file" option to jtreg.
