I have the following Java that tries to determine file type server side:
// BEGIN USER CODE
Core.getLogger(this.toString()).info("Starting...");
String retval=new String("");
InputStream is = Core.getFileDocumentContent(getContext(),obj_FileDocument.getMendixObject());;
try {
//File f = new File("data/tmp/a.jpg");
ContentHandler contenthandler = new BodyContentHandler();
Metadata metadata = new Metadata();
//metadata.set(Metadata.RESOURCE_NAME_KEY, f.getName());
try{
Parser parser = new AutoDetectParser();
ParseContext context=new ParseContext();
parser.parse(is, contenthandler, metadata,context);
/*
Core.getLogger(this.toString()).info("Mime: " + metadata.get(Metadata.CONTENT_TYPE));
Core.getLogger(this.toString()).info("Title: " + metadata.get(Metadata.TITLE));
Core.getLogger(this.toString()).info("Author: " + metadata.get(Metadata.AUTHOR));
Core.getLogger(this.toString()).info("content: " + contenthandler.toString());
*/
retval=metadata.get(Metadata.CONTENT_TYPE);
}catch (Exception e) {
Core.getLogger(this.toString()).info("Mime type exception: "+e.toString());
}
}catch (Exception e) {
Core.getLogger(this.toString()).info("Error in determining file type: "+e.toString());
}finally{
if (is != null) is.close();
}
Core.getLogger(this.toString()).info("Ending...");
return retval;
// END USER CODE
I get the following error when querying certain file types:

How can I handle this fatality that it does not shut down mendix runtime? Alternatively what filetype detection library can I use.
Thankyou
