Andy Seaborne commented on JENA-1582:
-------------------------------------
The code is (in Jena 3) trying to write in "pretty RDF/XML" whereas in 2.13.0
the default was plain RDF/XML.
Pretty RDF/XML can be expensive (in time and space)
Try:
{code:java}
try (OutputStream out = new FileOutputStream(f.toFile())) {
RDFDataMgr.write(out, model, RDFFormat.RDFXML_PLAIN);
}
{code}
Other points:
Buffering the output might help a little.
It is better to use Java `InputStream` and `OutputStream` than Java `Reader`
or `Writer` to write RDF, especially RDF/XML.

> Hello,
> Actually we try to migrate a project from an old version of Jena (2.13.0) to
> a more recent but we experienced some issue when we try to write the model
> with Model#write.
> With Jena 2.13.0 the model is written quite fast on the disk but with Jena
> 3.8.0, the process seems stuck into a loop and we reach an OOM Exception : GC
> limit exceeded.
> I've attach a small project to reproduce the problem. It contains the model
> (http___publications_europa_eu_resource_authority_language.rdf) and the code
> which simulate our behavior.
> Thanks for your help,
> Arnaud.
