Java code OK in AIX 3.5, fails in RHEL 7.5: It makes corrupt DOC, DOCX, XLS, XLSX files but good HTML files

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}

We have a Java process (see below) to generate DOC, DOCX, XLS, XLSX, and HTML and save it to our Linux PCs. It ran well in our old AIX 3.5 machine; but in our new RHEL 7.5 machine, Microsoft proprietary document formats (DOCX, DOC, XLSX, and XLS) it outputs are corrupt. HTML files are not corrupt.

I have downloaded the output files into a Windows PC and try to open them; Exception errors say the DOC/DOCX/XLS/XSLX files are corrupt and cannot be opened.

The Java code works well in the old Linux PC. I am assuming there might some libraries or software we need to install in the new PC.

Below is my java code (Process to generate the file)

int BUFFER_SIZE=1024*256;

           int bytesRead=0;

           Resultset rs=obj.resultSet();

           DocumentClass = new DocumentClass();

           ByteArrayOutputStream baos  = new ByteArrayOutputStream();

           byte[] buffer = new byte[BUFFER_SIZE];

           BufferedInputStream bis = new BufferedInputStream(rs.getBinaryStream(1));



           try

           {

                bytesRead = bis.read(buffer,0,BUFFER_SIZE);

                while (bytesRead > 0)

                {

                   baos.write(buffer, 0, bytesRead);

                   buffer = new byte[BUFFER_SIZE];

                   bytesRead = bis.read(buffer,0,BUFFER_SIZE);

                }

           }

          catch (IOException io ) 

           {

             System.out.println(io.getMessage());

           } 



           DocumentClass.setFileBody(baos);

           BufferedWriter CreateDoc = new BufferedWriter(new FileWriter("/usr/Test.docx"));

            CreateDoc.write(DocumentClass.getFileBody().toString());

            CreateDoc.close();

  Are you using the same java version? Maybe you are running a newer java version on RHEL that is not supported? Are the jars/.class files in the classpath the same? Do you have no logfile? What framework/library are you using (CreateDoc)?
