0047010: Running backoffice selenium tests fails with only openjdk-11-jre-headless installed but gui environment available

Description

Server environments typically only have the -headless variant of java installed (all except GUI parts).
Ubuntu java packaging until recently included some GUI libraries also in the -headless variant but just 'fixed' that issue.

However that break usecases which accidentally relied on the old behavior.

One of them is the the java.imageio.ImageIO code of the JDK auto-detect if it runs in a GUI environment (i.e. DISPLAY environment var set) and if it does requires the full java to be installed. When not running in an GUI it works without problems with only the -headless.

The Image.java class in our backoffice-tests is hit by this behavior change if run on our CI environment (as in there the GUI is available to be able to run firefox)

Steps To Reproduce

Have openjdk-11-jdk-headless installed
Do NOT have openjdk-11-jdk package installed

Run the following test (from configured backoffice-test workspace)
ant -f src-test/com/openbravo/test/integration/erp/modules/client/application/testsuites/navigationbarcomponents/build.xml test.integration.erp.modules.client.application.testsuites.navigationbarcomponents.NAV0140_CheckYourCompanyLogo

It fails with:
java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-11-openjdk-amd64/lib/libawt_xawt.so
at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2630)

Proposed Solution

Add -Djava.awt.headless=true argument to the JVM running the tests to tell java it is not running in a GUI environment.

Notes
(0129152) hgbot (developer) 2021-06-07 17:03	Repository: https://gitlab.com/openbravo/ci/backoffice-test [^] Changeset: 7ae511af90535d32dec88e9573a750ab22231776 Author: Stefan Huehner <stefan@huehner.org> Date: 2021-06-07T17:02:42+02:00 URL: https://gitlab.com/openbravo/ci/backoffice-test/-/commit/7ae511af90535d32dec88e9573a750ab22231776 [^] Fixes ISSUE-47010: Add java.awt.headless argument when running tests. Avoid error about java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-11-openjdk-amd64/lib/libawt_xawt.so happening when only having openjdk-11-jdk-headless (but not openjdk-11-jdk) installed while having GUI environment available. Set the headless flag unconditionally. As junit run is forked from inside ANT easiest is to add the flag directly in the build system. --- M build.xml ---
