Hi!
I am trying to read a xlsx-file whose size is 7.3M with POI version 3.15, here
is the code：
InputStream is = new FileInputStream(new File(path));//line 1
Workbook book = new XSSFWorkbook(in);// line 2
When running to line 2，the memory of javaw rised violently from 700M to
1200M，cpu from 10% to 90%，the following is the screenshot of memory dump:
In the picture, the object of Xobj$AttrXobj has more than 5 millions so that
it occupy the most of memory，but the file size is just 7.3M.
Can someone help me?
Thank you!
