> The Isolater.JdbcDelegate class's delegateWork(...) method leaves the JDBC Connection open causing a lekage. Specifically, the connection is left open only when the Connection was set to autocommit false.
> The escenario in which the problem is experienced is when a TransactionHelper subclass is implemented for instance to generate custom identifiers, the TransactionHelper provides the doWorkInNewTransaction method to ensure that the ID generation is done in a separate transaction and always commited. The mentioned method uses the Isolater class for this purpose.
