@bdesert @ottobackwards Thanks for reviewing. I've added unit tests.
As a reference, I run the added tests with Lexer before this PR. Following
tests failed with current Lexer, but passes with the updated Lexer:
This test failed with original Lexer because `[\s]` is converted to `[\\s]`
by Lexer and didn't match.
```
[ERROR]

org.junit.ComparisonFailure:

at
org.apache.nifi.record.path.TestRecordPath.testReplaceRegexEscapedCharacters(TestRecordPath.java:1046)
```
This test failed with original Lexer because `\[` is converted to `\\[` by
Lexer and produced RegEx syntax error.
```

Both tests failed with the same cause, and fixed by this PR.

> with replacement value strategy as Record Path Value,

> replaceRegex(/employeeName, "[\[]", "(")
> Processor is throwing following exception.
> RecordPathException: java.util.regex.PatternSyntaxException: Unclosed

> It worked fine with other special characters such as \{, }, <, >, ;, _, "
> For double qoute ("), i had to use single escape character, for above listed
> other characters, worked fine without any escape character. Other folks in
> Nifi Slack tried \s, \d, \w, \.
> looks like non of them worked.
> replace function worked for replacing [ and ]characters. didn't test any
