This artifact provides a BankleitzahlenVerzeichnis implementation backed by bankfiles. Bankfile resources are read using any available BankfileProvider implementation. The DefaultBankfileProvider implementation searches bankfiles at classpath location META-INF/jdtaus.
All released artifacts prior to 1.11 come with a set of default bankfiles. Starting with version 1.11 these default bankfiles are no longer part of the artifact's jar file. When upgrading your application to 1.11 you need to provide bankfiles yourself by either placing the files in the application's classpath for use by class DefaultBankfileProvider or by supplying a custom BankfileProvider implementation providing the bankfile resources. The former default bankfiles are available for download as a starting point from here.
