Description

When you try to change the case of a file via FileObject.moveTo(), VFS first deletes the target
file, which in a case-insentive FS is the same as the original and is left with nothing no files
anymore..

For example:

StandardFileSystemManager fileSystemManager
= new StandardFileSystemManager();

fileSystemManager.setCacheStrategy(CacheStrategy.ON_RESOLVE);
fileSystemManager.init();

FileSystemOptions fileoptions = new FileSystemOptions();
FileObject root = fileSystemManager.resolveFile("/tmp/", fileoptions);

File dummy = new File("/tmp/test.txt");
dummy.createNewFile();

Writer w = new FileWriter(dummy);
w.write("Some text");
w.close();

long size = dummy.length();

FileObject fo = root.resolveFile("test.txt");
FileObject fo2 = root.resolveFile("TeST.txt");

fo.moveTo(fo2);

At the end of the test, neither test.txt nor TeST.txt exists...
