ConcurrentModificationException
TDB + ConcurrentModificationException
-------------------------------------
Key: CLEREZZA-197
URL: https://issues.apache.org/jira/browse/CLEREZZA-197
Project: Clerezza
Issue Type: Bug
Reporter: Oliver Strässer
Priority: Blocker
After I changed the Actioncenter from sesame to tdb, i got the following Error:
java.util.ConcurrentModificationException
at com.hp.hpl.jena.tdb.store.GraphTDBBase$MapperIteratorTriples.checkCourrentModification(GraphTDBBase.java:209)
at com.hp.hpl.jena.tdb.store.GraphTDBBase$MapperIteratorTriples.hasNext(GraphTDBBase.java:217)
at org.apache.clerezza.rdf.jena.storage.JenaGraphAdaptor$1.hasNext(JenaGraphAdaptor.java:80)
at org.apache.clerezza.rdf.core.impl.AbstractTripleCollection$1.hasNext(AbstractTripleCollection.java:77)
at org.apache.clerezza.rdf.core.access.LockingIterator.hasNext(LockingIterator.java:47)
at
This problem occurs many times on different places and variations.
An error in the same category (i can't reproduce the situation) - occurs while reading the graph an iterating through the graph - with hasnext / next
the exceptions was something like "elemntmnotfound" at the next(method).
