DefaultBuildController.makeAndStoreBuildResult cannot save build result due to maximum size of COMMAND_LINE

Since the maven perforce scm provider creates temporary client specs with a long name (see below), the checkout command gets quite long, too, and hence cannot be save in the COMMAND_LINE column due to the maximum size of 256.

Here is the stack trace:
