Splitting of MsAccessConnectionProvider in 2 separate classes to read
data from an absolute path OR from a classpath resource. The latter is
needed by VmeReportsStoreGateway / Web in order to initialize the data
access layer. All previous tests relying on the old
MsAccessConnectionProvider have been transformed in order to use
CDIRunner as runner and the correct alternative
(FilesystemMsAccessConnectionProvider) has been explicitly selected.
This change also involved VmeReader. All current tests perform OK.
