Bug ID: 59166
Summary: util TempFile could cause memory leak
Product: POI
Version: 3.13-FINAL
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: POI Overall
Assignee: [email protected]
Reporter: [email protected]
Currently implementation will register not only temp directory, but also
individual files to java.io.DeleteOnExitHook via java.io.File#deleteOnExit
For some long running applications which generate tons of files via POI, it
will create huge garbage to the hook, even the actual temp files have already
been deleted.
Today, there is only one system property flag "poi.keep.tmp.files". If turn
off, both temp directory and temp files won't be deleted on exit. Can we always
ignore files, and only register temp directory?
