Cannot use XtextTest in pde build

Hi,

We are using XtextTest to test our DSL. It works fine in the IDE, but fails on 
our build server. The problem is the @BeforeClass call:
    @BeforeClass
    public static void init_internal() {
        new StandaloneSetup().setPlatformUri("..");
    }

The setPlatformUri("..") is not working on our tycho build because the current 
directory is set to our root build area. Therefore the .. initiate a scan of 
the whole build server projects (!).

Unfortunately, it is not possible to override the init_internal method as it is 
a static method. To workaround the issue, we duplicated the XtestTest class and 
remove the init_internal method.

What steps will reproduce the problem?
1. Create a working XtextTest test case
2. Run a pde build where you do not have the rights to folders next to your 
build area.

What is the expected output? What do you see instead?
1. I expect the test to succeed, instead I got the following stacktrace:
