Re: [dash-dev] Re: Athena: JUnit tests randomly failing to get launched
The testLocal does not work on Hudson, there has been a long standing issue open with the webmasters to change some configuration settings to allow it to work, no movement yet.

Could be a misconfiguration of the hudson server. Please report a bug:

Hi again,

I tried to use "testLocal" instead of "test", with xvnc enabled in
Hudson, as explained
in�http://wiki.eclipse.org/Common_Build_Infrastructure/Testing.
But I get the following blocking error:
Xlib: connection to ":20.0" refused by server
Xlib: No protocol specified

Did I do something wrong?

I also checked the logs of other jobs running on Hudson, and there still
seems to be many display-related errors:

    Hi,

    My build's JUnit tests randomly fail to get launched.
    I started the same build 4 times with the same configuration, and I
    got 3 different results!
    1: 3 test suites were launched
    2: 1 test suite was launched
    3: 12�test suites were launched�
    4:�1 test suite was launched

    In jobs 1,2 and 4, I got the following error messages:
    - The application 'Eclipse' lost its connection to the display
    localhost:9.0
    - Server is already active for display 9
    - Server is already active for display 21

    This looks like this is caused by display contention issues on the
build server, but now there seems to be a new problem since a few days: 
    I found the following errors in the build logs (that appear even in
the jobs that did pass all tests successfully!), in the testing part: 
    Could not load ${build.properties}
    and
    Could not load ${testing.properties}

    This started happening without any changes to the build
    configuration, so I suspect something else changed on the server.
    I looked in the build log of several other jobs on Hudson, and they
    have the same error
    (cbi-wtp-wst,�cbi-pdt-2.2-helios,�cbi-mat-nightly, ...).

    So, the build takes one hour to complete, with only one job
    succeeding once in a while, and with random issues popping up with
    no apparent reason.
    As a result, I am starting many builds until I get one that works,
    overloading the build server�uselessly, and�making it more difficult
    for everyone to prepare the incoming Helios milestone.
    That's why I am asking for your help in solving these issues.
