EVALUATION
The typo should be corrected as in description section.
*** (#1 of 1): [ UNSAVED ] ###@###.###

WORK AROUND
There is not a bug with the stop-world collectors.
With concurrent collectors, however, the typo leaves one vulnerable
to GC corruption. Fortunately, G1 has this flag switched off by default.
To work around the problem when using CMS, use -XX:-ReduceInitialCardMarks.
