javax.jdo.JDOFatalDataStoreException: No valid java.sql.Connection instances could be obtained from the DataSource It is happening sort of unpredictably. (I will try and get a better stack trace and repost.) We are using Oracle (8i) and I have tried artificially forcing kodo to not be able to obtain a connection in two ways: 1) by setting javax.jdo.option.MaxPool=1 javax.jdo.option.MsWait=0 but this just results in a different exception: A connection could not be obtained in the specified login time of 0 seconds.
