Jimmy Praet commented on VFS-297:
---------------------------------
I'm also running into this issue. And as a result each instance of
SftpFileSystem also opens a new SFTP connection. This is really a blocker.
> New instance of SftpFileSystem is created every time due to the bug in
> FileSystemOptions.compareTo()

> Key: VFS-297
> URL: https://issues.apache.org/jira/browse/VFS-297
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Kirill Safonov
>
> FileSystemOptions.compareTo() uses TreeMap's hashcode. This is not
> appropriate if map contains array instances since Array's equals() merely
> checks == (so that {{new Array[0].equals(new Array[0])}} is false).
> So when I configure FileSystemOptions like
> {{SftpFileSystemConfigBuilder.getInstance().setIdentities(options, new
> File[]{new File(privateKeyFile)})}} I never get filesystem instance reused.
