Hello,

we have a client who has the following set up: JTS ver. 4.0.2, RTC-BuildSystem-Toolkit-AIX-4.0.2 and RTC-scmTools-AIX-4.0.2 (command line build, Jazz build engine ).
They received an error message when trying to execute personal builds for the following test case:
Stream A- workspace A
Stream B- workspace B
Stream B was branched away from Stream A
Building from the workspace A works fine
Switch to workspace B and build for stream B works fine
Switch back to workspace A the error occurs: "

Does anybody have an idea why this happens?
