I made a benchmark with JMH which shows that the modified method is about 15% faster (see escapeRegex2 below) : Benchmark Mode Cnt Score Error Units CucumberExpressionBenchmark.escapeRegex0 thrpt 25 726563,091 ± 15558,020 ops/s CucumberExpressionBenchmark.escapeRegex1 thrpt 25 782046,026 ± 10993,804 ops/s CucumberExpressionBenchmark.escapeRegex2 thrpt 25 833512,235 ± 25088,968 ops/s The `CucumberExpression` class looks extensively tested, thus I didn't added more test cases. Note: for completeness, I tested another variant (escapeRegex1) which replaces the `ESCAPE_PATTERN.matcher(text).replaceAll(String)` with multiple `String.replace(String,String)` : the performance is not that good (only 8% faster than the original method) and code readability/maintenance is bad. But it was interesting to have the numbers to compare...

🤔 What's changed?
I rewrote a regular expression to improve
CucumberExpressioncreation performance.⚡️ What's your motivation?
My motivation is to have a better performance for the Cucumber framework.
I made a benchmark with JMH which shows that the modified method is about 15% faster (see escapeRegex2 below) :
Benchmark Mode Cnt Score Error Units
CucumberExpressionBenchmark.escapeRegex0 thrpt 25 726563,091 ± 15558,020 ops/s
CucumberExpressionBenchmark.escapeRegex2 thrpt 25 833512,235 ± 25088,968 ops/s
