Hi all, I'm finding I quite reguarly get this exception when I'm attempting to call PersistenceBroker.store(Object) from multiple threads simultaneously.
<?xml version='1.0'?> <exception> <cause> <detailMessage/> <exceptionClass>java.util.ConcurrentModificationException</exceptionClass> <stackTrace> <stackTrace>java.util.AbstractList$Itr.checkForComodification(AbstractList.j ava:444)</stackTrace> <stackTrace>java.util.AbstractList$Itr.next(AbstractList.java:417)</stackTra ce> <stackTrace>java.util.AbstractCollection.remove(AbstractCollection.java:250) </stackTrace> <stackTrace>org.apache.ojb.broker.core.PersistenceBrokerImpl.store(Unknown Source)</stackTrace> <stackTrace>org.apache.ojb.broker.core.PersistenceBrokerImpl.store(Unknown Source)</stackTrace> <stackTrace>org.apache.ojb.broker.core.DelegatingPersistenceBroker.store(Unk nown Source)</stackTrace> ... </stackTrace> </cause> <detailMessage>Failed to update History record java.util.ConcurrentModificationException</detailMessage> <exceptionClass>org.apache.ojb.broker.PersistenceBrokerException</exceptionC lass> <stackTrace/> </exception> Obviously somewhere in the broker there's been an attempt to modify the structure of a list by 2 or more threads simultaneously. My question is, has anything been done to prevent this in a newer version or should I just catch these exceptions and retry the store? I'm using ojb-1.0.rc3 at the moment.
