> trunk/messages.xml shows two messages that incorrectly refer to db2j:
> 42Y32=Aggregator class ''{0}'' for aggregate ''{1}'' on type {2} does not implement com.ibm.db2j.aggregates.Aggregator.
> There is now no class Aggregator in Derby. This message is generated from the class:
> org.apache.derby.impl.sql.compile.AggregateNode.java.
> private void checkAggregatorClassName(String className) throws StandardException
> {
> className = verifyClassExist(className, false);
> if (!classInspector.assignableTo(className, "org.apache.derby.iapi.sql.execute.ExecAggregator"))
> {
> throw StandardException.newException
> (SQLState.LANG_BAD_AGGREGATOR_CLASS2,
> className,
> aggregateName,
> operand.getTypeId().getSQLTypeName());
> }
> }
> The original in Cloudscape had a reference to an Aggregator class, the if looked like this:
> if (!classInspector.assignableTo(className, "com.ibm.db2j.aggregates.Aggregator") &&
> !classInspector.assignableTo
> (className, "com.ibm.db2j.protocol.Database.Language.Execution.ExecAggregator"))
> {
> throw StandardException.newException(SQLState.LANG_BAD_AGGREGATOR_CLASS2,
> ....
> Maybe the message now needs to mention org.apache.derby.iapi.sql.execute.ExecAggregator?
> But, I think maybe this message cannot be obtained unless someone introduces a bug within the Derby code. I think the reference to another internal class should be removed. Or maybe the text of Cloudscape message 42Y31 can be used: 42Y31=LANG_BAD_AGGREGATOR_CLASS="Aggregator class ''{0}'' for aggregate ''{1}'' on type {2} is inaccessable or does not exist."
> XSDB8.D=DATA_MULTIPLE_JBMS_FORCE_LOCK ="WARNING: Derby (instance {0}) is attempting to boot the database {1} even though Derby (instance {2}) may still be active. Only one instance of Derby should boot a database at a time. Severe and non-recoverable corruption can result if 2 instances of Derby boot on the same database at the same time. The db2j.database.forceDatabaseLock=true property has been set, so the database will not boot until the db.lck is no longer present. Normally this file is removed when the first instance of Derby to boot on the database exits, but it may be left behind in some shutdowns. It will be necessary to remove the file by hand in that case. It is important to verify that no other VM is accessing the database before deleting the db.lck file by hand."
> John Embretsen commented on this in DERBY-1838:
> https://issues.apache.org/jira/browse/DERBY-1838#action_12434090
> Indicating that not only should the message refer to derby.database.forceDatabaseLock, but the replacement of parameters is not happening either.
> But I can not find a place where this message is generated, so maybe it can just be removed.
