--- Comment #1 from Dominik Stadler <dominik.stad...@gmx.at> --- Unfortunately none of the few active committers has much knowledge in this area. This likely requires some digging into the inner workings of the format and how the data-structures are represented. The resulting file is actually corrupted, re-reading it via Apache POI fails, so it seems there is some corruption introduced by the replacing. Added a reproducer test-case via r1923055 and r1923063. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
