Sun.io.MalformedInputException

Question

I am trying to open a java source code in Oracle JDeveloper 9.0.3.1 and am receiving this exception!
What does this mean?
I am able to open the same java source code in any other normal text editor!
Is this a JDeveloper bug?

sun.io.MalformedInputException
This exception appears when running the follwing code:
inputReader is obtained from a document that is tranfered via FTP to IFS.
This error appears only when running on a Solaris platform (I tested with a windows platform and it work fine).
Oracle version is 9i, IFS1.1
Thanx This is how I obtain the Reader. This class is an Ifs Agent that respond to create events.
public void processEvent(IfsEvent event) throws IfsException{
Long objectId = event.getId();
PublicObject po = getSession().getPublicObject(objectId);
Document doc = (Document)po.getResolvedPublicObject();
BufferedReader br = new BufferedReader(doc.getContentReader());
someClass.readDocument(br);
public boolean readDocument(Reader inputReader){
FolderPathResolver resolver = new FolderPathResolver(ifsSession);
BufferedReader bufferReader=new BufferedReader(inputReader);
String line = "";
StringBuffer file = new StringBuffer(1024);
while ((line = bufferReader.readLine()) != null){
file.append(line);
I think that is something related to Reader but I don't know what....
