Henryk Konsek reopened CAMEL-5398:
----------------------------------


After playing more with CAMEL-5396, I come with conclusion that we could 
benefit from Pattern.compile() optimization in some cases.

I'm reopening this issue - I'll take a closer look at each individual case.
                
> Optimize String.replaceAll() to cache Patterns where suitable

> Inspired by issue [1] regarding performance of JMS headers, I performed a 
> little search in IDE and found out that there's pretty much not optimized 
> String.replaceAll() calls.
> I think it will be good to search the code base for such calls again and 
> replace them with references to the static pre-compiled 
> java.util.regex.Patterns. Of course if such action makes sense (like in 
> StringHelper#removeQuotes()).
