[jcifs] canRead always returning false

[Allen, Michael B (RSCH)]

If you can come up with a minimal code sample I'll take a look at this ASAP. Sounds like something funky is going on. About the second part, the attributes of an SmbFile are chached for a fraction of
a second. If you set attrExpirationPeriod to 0 does this still happen?
