follwing code try to find out sequance ja or JA or ja; , This sq. hasn;t in given string but still first line of code find it. Why? Looks like some problem with codl fusion expression builder

<cfset IndexOfOccurrence=REFind("[J|j;|&##x4A;|&##x6A;][A|a;|&##x41;|&##x61;]", "mamjsdjzdahggjxac;")>
<cfset myidex=REFind("[J|j;|&##x4A;|&##x6A;][A|a;|&##x41;|&##x61;]", "mamjsdjzdahggjqac;")>


Thanks
