SWTException in SWTBot-Test: Why is it thrown in Tycho+Surefire?

Question

I get an SWTException:Invalid thread access from all of my SWTBot-Test. They all turn green when they where started from eclipse, so the problem must be inside the pom.xml I guess. How to solve this?

I use the following arguments and dependencies in the pom.xml of the test-fragment:

Answer 2

How do you tell surefire which tests to run for you ? Did you configure following?

<configuration>
                ...
                <testSuite>bundle.symbolic.name.of.test.plugin</testSuite>
                <testClass>package.of.test.suite.YourTestSuiteOrClass</testClass>
                ...
</configuration>
