Using SizeAndTimeBasedFNATP I'm getting filename collisions on size-based rollover after restarting my process. I think the problem is in SizeAndTimeBasedFNATP.start:

if (tbrp.getParentsRawFileProperty() == null)

{ String regex = tbrp.fileNamePattern.toRegex(dateInCurrentPeriod); String stemRegex = FileFilterUtil.afterLastSlash(regex); computeCurrentPeriodsHighestCounterValue(stemRegex); }

shouldn't this be if (tbrp.getParentsRawFileProperty() != null)?
