[jira] [Updated] (JENA-487) CannotEncodeCharacterException when
writing lots of instances to file via RDFWriter
[ https://issues.apache.org/jira/browse/JENA-487?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andy Seaborne updated JENA-487:
-------------------------------
Description:
I'm using the following code to write a model to a file:
{noformat}
RDFWriter w = model.getWriter("RDF/XML"); //-ABBREV (abbrev will produce rdf:seq, the other wont)
w.setProperty("showXMLDeclaration", "true");
w.setProperty("showDoctypeDeclaration", "true");
w.setProperty("xmlbase", xmlBase);
File saveFile = new File(fileName);
FileOutputStream fso = null;
try {
fso = new FileOutputStream(saveFile);
} catch (Exception e) {
e.printStackTrace();
}
w.write(model, fso, "RDF/XML");
fso.close();
{noformat}
If I run this with 10000 instances it works, if I run it with 20000 instances the write fails with the following exception:
{noformat}
