--- Comment #6 from PJ Fanning <fannin...@yahoo.com> --- If you have lots of cell with values then you will use lots of memory. We have some protections against malicious inputs that might try to fool POI into creating large arrays but in the end of the day, if you have enough data in the xlsx, POI will run into issues holding it all in memory. The stacktrace in the description indicates that POI probably didn't even get as far as parsing the XML and creating the XMLBeans. org.apache.poi.openxml4j.opc.ZipPackage.setUseTempFilePackageParts(true) might help a little. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
