Hello,
In my application Java, I have a tool of migration which allows me to push
towards CouchDB (No-SQL DB) in JSON (Jackon), XML(JAXB), and PDF format
corresponding to these folders (POJOs/Object Java).
In the 500th iteration (approximately) the memory PermGen is saturated, and
the JVM is blocked(surrounded). It is necessarily necessary to restart the
JBoss server ...
We analyzed the evolution of the memory with JConsole (of the jdk) and also
JProfiler 8 => leak og PermGen memory ...
It would seem that JOpenDocument is not adapted in batch processing.
Here is a result of our UnitTest :
*The unit test :*
@Test
public void testDeCharge() throws DouaneException, JDOMException,
TemplateException, IOException {
DossierTestBuilder builder = new DossierTestBuilder();
List<Dossier> dossiers = new ArrayList<Dossier>();
dossiers.add(builder.getDossierComplet(TypeDossier.EXANTE));
dossiers.add(builder.getDossierComplet(TypeDossier.EXPOST1));
dossiers.add(builder.getDossierComplet(TypeDossier.EXPOST2_AUTRE));
dossiers.add(builder.getDossierComplet(TypeDossier.EXPOST2_FINANCE));
dossiers.add(builder.getDossierComplet(TypeDossier.TSVR));
int j = 0;
for(int i = 0; i < 1000; i++) {
for(Dossier dossier : dossiers) {
DossierEdition.getDossierEdition(dossier).editer(dossier);
j++;
log.info("Dossier " + j + " OK...");
}
}
}
*The console output : *
