While running a multi-threaded stress test, I received
the following exception:
java.lang.NullPointerException
at java.lang.Throwable.<init>(Throwable.java)
at java.lang.Throwable.<init>(Throwable.java)
at
java.lang.NullPointerException.<init>(NullPointerException.java:60)
at
org.apache.ojb.broker.accesslayer.RsIterator$ResourceWrapper.beforeClose(RsIterator.java)
at
org.apache.ojb.broker.core.PersistenceBrokerAbstractImpl.notifiyStateListener(PersistenceBrokerAbstractImpl.java)
It looks like "ref" or "ref.get()" became null after
the check in the following method:
public void beforeClose(PBStateEvent event)
{
if(ref != null && ref.get() != null)
{
((RsIterator)ref.get()).releaseDbResources();
ref = null;
}
}
Is there a need to synchronize on the object(s)?
