           Summary: [PATCH] Merge cell ranges broken
           Product: POI
           Version: 3.16-FINAL
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: SS Common
          Assignee: dev@poi.apache.org

Created attachment 35496
  --> https://bz.apache.org/bugzilla/attachment.cgi?id=35496&action=edit
patch created using "ant -f patch.xml"

The merge functionality of cell ranges in
org.apache.poi.ss.util.CellRangeUtil.mergeCellRanges(CellRangeAddress[]) is
broken: some of the provided input cell ranges get lost during merge under
circumstances.

Example: Merge of cell ranges (A1), (B1) and (A2) results in cell ranges
(A1:A2). (B1) gets lost.

The Patch provides test cases revealing the broken merge functionality and
testing its fix in CellRangeUtil. The patch was created using "ant -f
patch.xml".
