Some days ago we upgraded from clearcase plugin 1.3.6 to 1.4.
We now noticed the following behavior:
Cleartool stops the update if the configspec is defect (such as a file referenced in load rules does not exist in clearcase) - no file gets updated.
But Jenkins continues the build with the old files existing in workspace (we use the "use update" function) and reports a green build (if the last build was green).
This load rule error is fatal and should stop the build.

SAMPLE:
Configspec:
element * CHECKEDOUT
element * /main/LATEST

Loadrules:
\SPCSDev\Tools\jenkins\Testfiles\Samplefile.txt
\SPCSDev\Tools\jenkins\Testfiles\NotexistingFile.txt

==>SampleFile.txt exists in clearcase, NotexistingFile.txt doesnt

Console out:

2. Actions taken to update the view:

3. NonfileError: "cleartool: Error: Unable to lookup "NotexistingFile.txt" in "\SPCSDev\Tools\jenkins\Testfiles@@\main\5": No such file or directory."
   NonfileError: "cleartool: Error: Unable to access "\SPCSDev\Tools\jenkins\Testfiles\NotexistingFile.txt": No such file or directory."
   NonfileError: "cleartool: Error: 1 config spec load rule problems encountered."

5. Update session status:
