[tycho-dev] Why is "HeadlessTestApplication" launched as a singleton

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

I'm trying to run an Equinox-OSGi-Application as an automated test
through PDE and through maven-tycho:

In PDE I launch the test suite using
org.eclipse.pde.junit.runtime.coretestapplication which is defined like
this:

>    <extension
>          id="coretestapplication"
>          point="org.eclipse.core.runtime.applications">
>       <application
>             visible="false">
>          <run
>                class="org.eclipse.pde.internal.junit.runtime.CoreTestApplication">
>          </run>
>       </application>
>    </extension>

which means I can launch inside my JUnit-Test my own OSGi-Application
when I run inside the eclipse IDE through the PDE-Junit-Plugin.

In contrast when running in maven, I launch the
org.eclipse.tycho.surefire.osgibooter.headlesstest which is defined like
this:

> <extension
>          id="headlesstest"
>          point="org.eclipse.core.runtime.applications">
>       <application
>             cardinality="singleton-global"
>             thread="main"
>             visible="true">
>          <run
>                class="org.eclipse.tycho.surefire.osgibooter.HeadlessTestApplication">
>          </run>
>       </application>
>    </extension>

which does not allow me to bring up another OSGi-Application. Is there a
reason you made the headlesstest a "singleton-global" or asked the other
way round: Are you open to change this?
