Re 4: I think that if one is wise enough to write a RegExp, they could use
"|" to combine several patterns, and do not really need splitting by comma. Or
do you envision a use case, where different types of patterns are used
together, and one of them is a regular expression?
I mean: do a .startsWith("/") && .endsWith("/") test before calling
String.split(). Skip splitting.
```diff
- if (null == patterns || 0 == patterns.trim().length()) {
+ if (null == patterns || 0 == (patterns = patterns.trim()).length()) {
...
- String values[] = patterns.split(",");
+ String values[] = patterns.startsWith("/") && patterns.endsWith("/") ? new
String[]{ patterns } : patterns.split(",");
```
