During CVS checkout we see the exception below. This seems to happen on every 2nd build or so. Build stops and we have to run it again.
We recently upgraded from an older version of CVS ( 1.6 ) and jenkins 1.389 or so. This happens on all builds using CVS.

FATAL: 1
java.lang.ArrayIndexOutOfBoundsException: 1
