Fixed inefficient usage of `String#replaceAll()` (Sonar)


ImportanceReview GuidanceRequires Scanning Tool
MEDIUMMerge Without ReviewYes (Sonar)

This change replaces String#replaceAll() with String#replace() to enhance performance and avoid confusion.

The String#replaceAll() call takes a regular expression for the first argument, which is then compiled and used to replace string subsections. However, the argument being passed to it doesn't actually appear to be a regular expression. Therefore, the replace() API appears to be a better fit.

Our changes look something like this:

    String init = "my string\n";

- String changed = init.replaceAll("\n", "<br>");
+ String changed = init.replace("\n", "<br>");
