I have used Apache POI for creating .xlsx files. I tried with POI 3.8 version but it has the memory leakage issue(It creates temp files and take large amount of time to create excel file). Now I am using POI 3.9 version, but it also shows the memory leakage issue same as in 3.8 version. I tried to retrieve 10000 records from DB and creates Excel file, It took around one hour time to create the file. **
Is there any new function or new package available in 3.9 version for resolving the memory leakage issue??
