Thanks [~krummas] for the fix.
Seems the following position will cause an assertion exception and fail the test: {{2, 3, 114, 115}}.
[test code|https://github.com/cooldoger/cassandra/commit/32e01cf4d144625eeec207708d90242f195e21b9]. Command to test:
{noformat}
$ for i in {0..180}; do echo == $i; ant test -Dtest.name=BlacklistingCompactionsTest -DTest.BadPos=$i >> /dev/null 2>&1 && echo "okay" || echo "failed"; done
{noformat}
