[jira] Reopened: (DERBY-2556) Code paths for db restore do not use doPrivileged-calls, causing SecurityException

["Daniel John Debrunner (JIRA)" <ji...@apache.org>]

Daniel John Debrunner reopened DERBY-2556:
------------------------------------------


PrivilegedFileOps is a utility class with privileged blocks which is strongly discouraged by Java docs (see comment in DERBY-3745).

This fix needs to be re-worked to not open uch security holes.

> When using 'createFrom' or 'restoreFrom' in the JDBC url to restore a database from a backup image, a SecurityException is thrown even though the policyfile for codebase derby.jar is correctly configured (giving Derby access to the backup image).
> A few comments on this issue can be found here (and in subsequent comments): https://issues.apache.org/jira/browse/DERBY-1001#action_12439811
> A workaround is wrapping the connection call in doPrivileged at the "application-level code", or granting the required permissions to the application codebase as well.
