We have encountered a problem in using eclipseLink when we do intensive reading operations.
This exception occurs now and then in production environment and is not reproducible in a simple test.
Here is the stacktrace:
Exception [EclipseLink-6168] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.QueryException
Exception Description: Query failed to prepare, unexpected error occurred: [java.lang.NullPointerException].
Internal Exception: java.lang.NullPointerException
Query: ReadAllQuery(name="ResourceAclData.getAclForOneResource" referenceClass=ResourceAclData sql="SELECT ID, OWNER_USER_ID, RESOURCE_ID, RESOURCE_TYPE_ID, VERSION FROM RESOURCE_ACL WHERE ((RESOURCE_TYPE_ID = ?) AND (RESOURCE_ID = ?))")

I think the problem is in
org.eclipse.persistence.internal.expressions.DataExpression.copyCollection(DataExpression.java:132) //derivedExpressions has a null elemment
at org.eclipse.persistence.internal.expressions.ObjectExpression.postCopyIn(ObjectExpression.java:470) // derivedExpressions is the member field of ObjectExpression.
In EclipseLink they use a NonSynchronizedVector,which I think maybe is the problem,but I can not find how the problem generated.
Has anyone encounter this problem before?
