File name parsing issues in layered file systems
------------------------------------------------
Key: VFS-225
URL: https://issues.apache.org/jira/browse/VFS-225
Project: Commons VFS
Issue Type: Bug
Affects Versions: 1.0
Environment: Windows XP SP2 - but also assuming in other environments
Reporter: Jens Scheffler
The "!" character is used as delimiter for e.g. ZIP file access as VFS
component.
When trying to traverse a layered file, e.g. traversing a ZIP content and the
ZIP contains a file with a "!" in the file name itself then a
FileSystemException appears - it seems that the parsing routine for layered
filenames is stumbling over the "!" character.
Exception trace for a test VFS component:
org.apache.commons.vfs.FileSystemException: Incorrect file system URI
"syncdb:file:///C:/Temp/test.xml!/c/temp/Maps/Important to Read!!/" in name
"syncdb:file:///C:/Temp/test.xml!/c/temp/Maps/Important to Read!!.txt", was
expecting "syncdb:file:///C:/Temp/test.xml!/".

(...)
As the accessing code was just traversing a folder tree with no chance to
handle this, is there any alternative for traversing through these layered file
systems when the content contains special characters?
Maybe the approach for parsing needs to be enhanced also, I could offer some
help but maybe need a hint to contribute a fix.
