When installing ER4 from install then a user can configure a datasource to be used by some of the components. The problem is that the default value that relates to h2 used absolute paths for directory locations where the data files will be stored. Those paths point to 'data' dir in the server. So when the directory where server is located is renamed, then the paths are no longer valid. The configuration should use jboss.server.data.dir by default to point to data dir instead of the absolute path.
Fixed for ER6 or later builds.
