23 * Thrown when there are troubles working with local file. Most likely (but not necessarily) wraps IOException. Might be
24 * perceived as specialized IOException with optional File and other repository information.
25 *
26 * <b>Hg4J</b> tries to minimize chances for IOException to occur (i.e. {@link File#canRead()} is checked before attempt to
27 * read a file that might not exist, and doesn't use this exception to wrap each and any {@link IOException} source (e.g.
28 * <code>#close()</code> calls are unlikely to yield it), hence it is likely to address real cases when I/O error occurs.
29 *
30 * On the other hand, when a file is supposed to exist and be readable, this exception might get thrown as well to indicate
31 * that's not true.
