[jcifs] Bug in SmbFile.getName() ??

[Jake Goulding]

To chime in, this bug has also hit us, but the rate it occurs is very
low. Windows explorer trims spaces when you create files, so you have to
jump through hoops to create such a file.

The name gets trimmed in the URL class, expanded and assigned to the local vars cannon and url (not the same values, but trimmed). The only var which gets assigned the real name (plus "\\") is unc. Now when calling the getName() function you are first checking the getUncPath0(), but since the unc is not null, nothing happens there and if, you would still use the url to initialize cannon, share and unc.
