Don't have the exact details, but remember noticing it a while ago. I think the store transaction context closes the transaction on such an error, while the language conneciton context just rollsback the transaction or the statement. I think the best and consistent approach would be to close the connection.

ASF	#453395	Thu Oct 05 21:40:18 UTC 2006	djd	~~DERBY-1732~~ 1. Make change to GenericStatementContext.isLastHandler() so it will return false for JVM errors thus allowing the outer contexts to take corrective action. 2. Store transaction context treats JVM errors as session severity. To ensure consistency, map severity for non StandardException instances to be SESSION_SEVERITY in GenericLanguageContext, and GenericStatementContext.
