In attached screenshot there is an example of incorrect highlighting of an opening of a tag.
"<meta" should be highlighted instead of "<s:property"
And here is a jsp code for the reference.
<s:if test="what!=null and perform==null">
<t:put param="page_head">
<meta http-equiv="Refresh"
content="0; url=<kk:url name="<%=UrlMapping.fill.getName()%>">
<kk:param name="what"><s:property value="what"/></kk:param>
<kk:param name="perform">perform</kk:param>
</kk:url>"/>
</t:put>
</s:if>
