Comment 1 _ pkuzel 2002-05-02 13:11:12 UTC 
nbfs:QBdataQBcvsQBnb34QBnb_allQBxml/api/doc/changes/../../../../openide

It is caused by fact that mounted FS is mounted too deep.
URI should throw an exception to allow handling.

WORKAROUND:
Execute the action at a filesystem that is mounted at shallower
parent.
Comment 2 _ pkuzel 2002-06-10 16:01:51 UTC 
While fixing it try to use FileUtil.toFile().toURL(). It is not bullet
proof but it should work well for LocalFilesystem.
Comment 3 _ lkramolis 2002-06-11 11:04:17 UTC 
Whenever possible "file:" URL used.
Comment 4 Martin Schovanek 2002-11-06 12:46:01 UTC 
VERIFIED
Comment 5 Quality Engineering 2003-07-02 08:38:51 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
