Description Vladimir 2019-06-03 15:32:25 UTC
I have a problem with autoSizeColumn with small number of columns and data.
I have an application which generates XLSX files in different threads. 
I have changed the POI version from 3.17 to 4.1.0 and the application became to hang on the autoSizeColumn(sheet, true) line. 
When I had removed this line or had changed to sheet.setColumnWidth(i, SMALL_COLUMN_WIDTH) the problem was resolved.

There aren't excpetions in the log file!

Small clarification: autoSizeColumn() works fine wit POI version 3.17 and Java 8

Can you provide a small sample application which reproduces the problem? Without it is very hard to investigate such a bug-report.
