We have configured a job to run tests against our various environments. This job is enabled to run builds in parallel if needed.

When we do run builds from this job in parallel, some of the tests fail with exceptions like the one below:

{{com.test.WebClientException: Failed trying to upload file '1360084126523_missingCols1.csv' for datasource 'M-0000019b-0000-0005-0000-0000000014a6'

The main issue here is:

java.io.FileNotFoundException: /jenkins/workspace/QE_All_Tests%402/target/test-classes/datasets/dataimport/incremental/INCMH10/missingCols1.csv (No such file or directory)

This happens because the test expects the file to be present at /jenkins/workspace/QE_All_Tests%402/ where as it's actually present at /jenkins/workspace/QE_All_Tests@2/

Jenkins should consider using some character other than '@' (e.g. '_') when creating workspaces for concurrent builds.
