Hi Kanstantin...
It is an open source project...and i also figured out what the problem is.
We have this section in the pom, to limit the resouces used for testing,
since we require an expensive tool (ClearCase UCM) to run on the machine as
well.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.19</version>
<configuration>
* <forkCount>1</forkCount>*
* <reuseForks>true</reuseForks>*
<argLine>-Xms512m -Xmx512m -Xss1m</argLine>
</configuration>
<executions>
<execution>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
The lines i marked with bold seems to be completely ignored in Java 8, it
spawns multiple java processes on the slave and eventually starves the
slave for memory, which causes the tool (ClearCase UCM) to behave
erratically which results in wierd Interrupted exceptions during build:

I fixed it by not running the tests using Java 8, 7 is ok since we came
from 6.
Best regards,
