How to update excel metadata using java - excel

Question

I am trying to update excel metadata in java using apache POI. Input file is large containing 8K columns and 600 rows. I am using below code
OPCPackage pkg = OPCPackage.open(new File("path for input"));
POIXMLProperties props = new POIXMLProperties(pkg);
props.getCoreProperties().setTitle("Test Title");
XSSFWorkbook wb = new XSSFWorkbook(pkg);
FileOutputStream fos = new FileOutputStream("path for output");
BufferedOutputStream bos = new BufferedOutputStream(fos);
wb.write(bos);
fos.close();
Above code is throwing me Out Of memory exception as below.

Could you please help to overcome this issue for updating excel properties ?

If you're just changing the OPC level metadata, there's no need to load the file up in the XSSF layer at any point. You'd only need to do that if you also wanted to change the spreadsheet contents eg cells
Your code can be as simple as
OPCPackage pkg = OPCPackage.open(new File("path for input"));
POIXMLProperties props = new POIXMLProperties(pkg);
props.getCoreProperties().setTitle("Test Title");
props.commit();
pkg.close();
