If the debug line is
log.debug("Cache: {}", getCache())
then I think the problem could be, that the cache gets modified, while
log4j is trying to print it and thus might throw a modification exception.
This log message is a small leftover from my tries and a) should be
guarded by a log.isDebugEnabled() call and b) should probably be removed.
