Description Javen O'Neal 2016-03-22 08:47:26 UTC 
Bug 58885 added addMergedRegionUnsafe and validateMergedRegions methods to XSSFSheet to allow merged regions to be added to a worksheet without checking for overlapping regions (which produces a workbook that Excel complains is a corrupt).

These methods should be promoted to Common SS so that HSSF and SXSSF can also avoid a potentially expensive check.
