Description Bernhard Seebass 2014-04-24 12:35:24 UTC 
getDataFormatString may return random results due to the unsynchronized usage of the static fields lastDateFormat, lastFormats and getDataFormatStringCache.

The methods getDataFormatString and cloneStyleFrom should use

synchronized (HSSFCellStyle.class) {
...
}
Comment 1 Dominik Stadler 2014-05-26 20:17:27 UTC 
I hopefully just fixed via Bug 56563 albeit a bit differently to avoid the expansive synchronization at this point.
