FilesScanner Tokenizer does not work well with input containing delimiter characters

this.files = new File[Tokenizer.tokenize(fileNames, Tokenizer.COMMON_DELIMITERS).length];
for (int i = 0; i < files.length; i++)

{ files[i] = new File(fileNames[i]); }

This code has multiple problems:

* The result of Tokenizer.tokenize is not used, only the length is taken. For the input "someFile;anotherFile", this leads to a ArrayIndexOutOfBoundsException, because the files-Array has size 2, but only fileNames[0] can be read, which won't even resolve to a file, because it has not been split.
* COMMON_DELIMITERS contains the space character, which can easily be contained in a single file name. On Windows, this is quite common with "C:\Program Files\...".
