--- Comment #4 from lwd <a96219...@gmail.com> --- (In reply to PJ Fanning from comment #3) > In ran the test case on my Macbook and it worked ok. No exceptions and wrote > out the xlsx file. I made no modifications to the code to get it to work. Sorry, a description of jvm parameters is missing. I am testing the effect of useTempFilePackageParts=true on the jvm heap memory usage, which works fine when the jvm parameter -Xmx1000M is set, and the above error occurs when -Xmx100M is set. And I noticed that it worked fine when the jvm parameter -Xmx1000M was set, But by setting the TempFile as expected. SetTempFileCreationStrategy (new DefaultTempFileCreationStrategy (tempDir)); The temporary files in the specified temporary directory are not deleted correctly. In my example I use var wb = new SXSSFWorkbook(1) to build a blank excel file, and I end up calling this._wb = new XSSFWorkbook() to build a blank excel file. In the method of new XSSFWorkbook () used in newPackage (XSSFWorkbookType workbookType) method through UnsynchronizedByteArrayOutputStream constructs a in the memory OPCPackage object. I updated my example to add an OPCPackageTest class. In this class I first create a blank excel file and then open it through SXSSFWorkbook and write the relevant data. github address:https://github.com/a96219/TempFilePackagePartsError/blob/main/src/main/java/org/example/OPCPackageTest.java Set the JVM parameter - Xmx100M then run org. Example. OPCPackageTest. The main method.
