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);
