Bug ID: 65260
Summary: Issue
Product: POI
Version: 4.1.2-FINAL
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: SXSSF
Assignee: dev@poi.apache.org
Reporter: kurets.a...@gmail.com
Target Milestone: ---
Good day.
We use Apache POI 4.1.2 for creation .xlsx file.
Our application starts inside Docker container.
We use open-jdk(11th version) without predefined fonts. We needs that for
security reason.
At firts time we used XSSFWorkbook/XSSFSheet. All worked correctly.
For reducing of memory usege we replaced XSSFWorkbook by SXSSFWorkbook.
After that we have next exception.
java.lang.InternalError: java.lang.reflect.InvocationTargetException

How we understand that relates with missing fonts and AutoSizeColumnTracker in
SXSSFSheet.
public SXSSFSheet(SXSSFWorkbook workbook, XSSFSheet xSheet) throws IOException
{
this._workbook = workbook;
this._sh = xSheet;
this._writer = workbook.createSheetDataWriter();
this.setRandomAccessWindowSize(this._workbook.getRandomAccessWindowSize());
this._autoSizeColumnTracker = new AutoSizeColumnTracker(this);
}
This constructor has initialization of AutoSizeColumnTracker.
AutoSizeColumnTracker calculates defaultCharWidth.
Why does SXSSFWorkbook need in AutoSizeColumnTracker by default?
How can we disable that or maybe set custom defaultCharWidth without
calculation?
