---------------------------------
Resolution: Fixed
Committed revision 1339256.
> CompressedFileFileObject Exception thrown when container file has no extension
> ------------------------------------------------------------------------------
>
> Key: VFS-408
> URL: https://issues.apache.org/jira/browse/VFS-408
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Anil Mahajan
> Priority: Minor
>
> CompressedFileFileObject blindly performs a substring operation on an
> unchecked String index lookup value. If that value happens to be -1 (lookup
> not found), then an Index Out Of Bounds error is thrown. The lookup is for a
> "." to find the base file name.
> This happens when trying to decompress a file with no file extension.
> subversion revision: 1159220 for CompressedFileFileObject.java
> code in repository: line 42:
> // todo, add getBaseName(String) to FileName
> String basename = container.getName().getBaseName();
> int pos = basename.lastIndexOf('.');
> basename = basename.substring(0, pos);
> should alter that last line to something like:
> if (pos > 0)
> basename = basename.substring(0, pos);
