Henri Yandell commented on LANG-1010:
-------------------------------------
A bit sloppy, but I was thinking of something akin to not escaping an & when it
forms the start of one of /&[a-zA-Z0-9]*;/ and /&#[0-9]*;/
Agreed that the caller should typically provide unescaped Strings.
> StringEscapeUtils escapeXml escapes already escaped characters
