File which the code fails

I'm extracting the text from a WordExtractor class (apache POI), but I have an error for some .doc files. Here the code:

"

	}

	    for (File file : files) {

        				String T = we.getText().replaceAll("\\n", " ").replaceAll("\\r", " ");
        				
            			// PARA ESCRIBIR EL ARCHIVO

	       		}
	    	}
	}

For most .docx and .doc files it's work fine.

The error message is:

Exception in thread "main" java.lang.RuntimeException: 
java.lang.IllegalArgumentException: The end (4958) must not be before the start (4990)

How can I fix it?
