Bug ID: 56537
Summary: Using
org.apache.poi.ss.usermodel.WorkbookFactory.create(Fil
e) leaks file handles
Product: POI
Version: 3.10
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: POI Overall
Assignee: [email protected]
Reporter: [email protected]
According to the API docs for XSSFWorkbook (
http://poi.apache.org/apidocs/org/apache/poi/xssf/usermodel/XSSFWorkbook.html#XSSFWorkbook%28java.lang.String%29
), "OPCPackage.close()" needs to be called when interaction with the Workbook
is complete.
It's not possible to do that when using
org.apache.poi.ss.usermodel.WorkbookFactory.create(File), so it presumably
leaks in the same way that the deprecated XSSFWorkbook(String) constructor
does.
It looks like same issue exists in the HSSFWorkbook() implementation for that
method too - leaking the file handle in NPOIFSFileSystem.
