Bug ID: 60010
Summary: SXSSFWorkbook.write() fails when the template is based
on PackageAccess.READ OPCPackage
Product: POI
Version: 3.14-FINAL
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: SXSSF
Assignee: [email protected]
Reporter: [email protected]
Observed behavior:
When a SXSSFWorkbook workbook is created from a template which is "read-only"
(initiated with PackageAccess.READ mode OPCPackage), then writing that workbook
to another file is failing.
Expected behavior:
Since the SXSSFWorkbook is written to another file - it should be possible to
save it even when the template has been open in read only mode.
Stack trace:
Exception in thread "main"
org.apache.poi.openxml4j.exceptions.InvalidOperationException: Operation not
allowed, document open in read only mode!
