Yes, these messages are still true. Sad to say that, but I realized that too late and planned to fix this, which is not that easy. Using any thing else than the SoftRefFilesChache will introduce memory leaks as the file-system object will not be discarded. You have to call close() on the filesystem, or even better call close on the DefaultFileSystemManager at all and do not use the VFS.getManager() singleton approach. That will also ensure that each and every resource used by the underlaying libraries are closed then too.
