Write to static field org.eclipse.egit.ui.internal.synchronize.model.GitModelRootTest.repo2 from instance method org.eclipse.egit.ui.internal.synchronize.model.GitModelRootTest.setupEnvironment()
 This instance method writes to a static field. This is tricky to get
correct if multiple instances are being manipulated,
and generally bad practice.
