------------------------------------------------------------------
Another issue I found recently which might be related to this problem:
Surefire 2.19.1 skips some test class randomly (no execution log on console log
itself, In all occurrences till now I found, one test class gets missed
completely), and causes coverage drop. It happens once in 20 builds. Surefire
does not detect any abnormally for those cases and passes the build.

Another issue I found recently which might be related to this problem:
Surefire 2.19.1 skips some test class randomly (no execution log on console log
itself), and causes coverage drop. It happens once in 20 builds. May be
frequency is more as we have ~13k unit tests, which runs in 12 jvms (in
parallel). Surefire does not detect any abnormally for those cases and passes
the build.
