I haven't started debugging this fully yet, but on a production system
that is taking a couple thousand hits a day (which all hit the
DB/Cayenne stack), and which has been deployed for months now, we all
of sudden started receiving this exception on just about every write
operation:
exception: [v.1.2M11 February 13 2006]
java.lang.IllegalArgumentException: DataDomain can only work with
DataContext. Unsupported context type: null
org.objectstyle.cayenne.access.Transaction.onQuery(Transaction.java:218)
org.objectstyle.cayenne.access.DataDomain.onQuery(DataDomain.java:721)
org.objectstyle.cayenne.access.DataRowStore.getSnapshot(DataRowStore.java:355)
org.objectstyle.cayenne.access.ObjectStore.getSnapshot(ObjectStore.java:855)
org.objectstyle.cayenne.access.ObjectStore.resolveHollow(ObjectStore.java:1066)
org.objectstyle.cayenne.access.DataContext.prepareForAccess(DataContext.java:1660)
org.objectstyle.cayenne.CayenneDataObject.readProperty(CayenneDataObject.java:238)
Restarting the app server magically fixed the problem :)
Any idea what might have happened to trigger this for writes (while
reads are fine) across all DataContexts?
