Martin Gainty commented on JBSEAM-4822:
---------------------------------------
every RE parser I have used expects RE reserved characters to be escaped
otherwise the parser will try to perform some action such as replacing the token
with a new token
escape the character ; to \;
and retry

> It was split on four parts:
