Getting error with Apache POI which is not able to read file passed using FileInputStream

问题

While executing below code,

FileInputStream fis = new FileInputStream("C:\\Users\\deepa\\Downloads\\TestDocument.xlsx");
        XSSFWorkbook workbook = new XSSFWorkbook(fis);

I am getting error as

InputStream of class class org.apache.commons.compress.archivers.zip.ZipArchiveInputStream is not implementing InputStreamStatistics.

I have included all the apace poi jar files and common -compress jar file. Please help.

Not a java expert of any sorts, but I use Selenium for test automation and was also getting this error. Somehow I found a solution:

1. Open the .classpath file with a file editor.
2. Cut your classpathentry that contains commons-compress-1.18.jar and paste it at the beginning below classpathentry kind="con"path="org.testng.TESTNG_CONTAINER"
3. Save and retry your program.

It solved my problem. Sorry I can't explain why (I am not a real programmer).
