Comment (by iwakeh):

 Didn't have time for testing, but switching from commons-lang to commons-
 lang3 might be a good choice in addition to your patch.
 The switch to commons-lang3 ([https://commons.apache.org/proper/commons-
 lang/article3_0.html lang3 changes]) contained a complete rewrite of
 'StringEscapeUtils'. And, I remember that I saw some good effect on using
 less 'String's during runtime in a former project.

 Code changes would only be the import statements

 {{{
  -import org.apache.commons.lang.StringEscapeUtils;
  -import org.apache.commons.lang.StringUtils;
  +import org.apache.commons.lang3.StringEscapeUtils;
  +import org.apache.commons.lang3.StringUtils;
 }}}

 classpath

 {{{
  -      <include name="commons-lang-2.6.jar"/>
  +      <include name="commons-lang3-3.1.jar"/>
 }}}

 and

 {{{
 -    return StringUtils.replaceEach(StringEscapeUtils.escapeJavaScript(s),
 +    return StringUtils.replaceEach(StringEscapeUtils.escapeEcmaScript(s),
 }}}

 as well as the corresponding unescapes  (and the addition of the debian
 package).

 Might be worth a try?
 commons-lang is only used for un/escaping.
