In http://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html (and the same for 7),
section for -XX:StartFlightRecording / maxsize,
it states:

"Specifies the maximum size (in bytes) of disk data to keep before it is flushed from the thread buffer to the global buffer......."

This is not correct.

The texts for maxsize (and also maxage) under -XX:StartFlightRecording should be the same as the texts under -XX:FlightRecorderOptions
