Hi
I am using apche poi ooxm-5.2.3 version and i was tried older version also.
I have used apache poi for reading the xlsx sheets and removing the selected
tabs that is working fine after deletion the save not happen it throwing the
following error.
org.apache.poi.openxml4j.exceptions.InvalidOperationException: A part with the
name '/docProps/core.xml' already exists : Packages shall not contain
equivalent part names and package implementers shall neither create nor
recognize packages with equivalent part names. [M1.12]

So as per my understanding whenever edit happens using the apche poi it try to
create new OPC package part checks existing part so that time the error
displayed.
For testing purpose i have deleted the package part then it was allowed for
SAVE.
The JAVA code is pretty straight forward.
try {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
XSSFWorkbook testWorkBook = new XSSFWorkbook(inputfile);
testWorkBook.removeSheetAt(0);
testWorkBook.write(bos);
}
catch(Exception e) {
e.printStackTrace();
}
Observations:
1.Once opened XLSX even without change also not allowed for save
2.The part name removal working only for windows Environment not LINUX server
