XYZ cannot be cast to javax.servlet.jsp.tagext.Tag
I compared one of the failing fragments in generated by 4.0.40 with equivalent fragment compiled in 4.0.45
Fragment from 4.0.40, notice the use of TagAdapter:
_jsp__xyz__tag_26 = new _jsp._WEB_22dINF._tags._xyz__tag();
_jsp__xyz__tag_26.setJspContext(pageContext);
_jsp__xyz__tag_26_adapter = new javax.servlet.jsp.tagext.TagAdapter(_jsp__xyz__tag_26);
_jsp__xyz__tag_26.setActiveTest(_caucho_expr_2.evalString(_jsp_env));
_jsp__xyz__tag_26.setJspBody(_jsp_fragment_0 = createFragment_0(null, _jsp_parentContext, pageContext, _jsp__xyz__tag_26_adapter, getJspBody(), _jsp_state, _jsp_pageManager));
Fragment from 4.0.45:
_jsp__xyz__tag_26 = _jsp_state.get_jsp__xyz__tag_26();
com.caucho.jsp.PageContextWrapper _jsp_context42
= _jsp_pageManager.createPageContextWrapper(pageContext);
_jsp_context42.setAttribute("activeTest", _caucho_expr_2.evalString(_jsp_env));
_jsp__xyz__tag_26.setActiveTest(_caucho_expr_2.evalString(_jsp_env));
_jsp__xyz__tag_26.setJspBody(_jsp_fragment_0 = createFragment_0(_jsp_fragment_0, _jsp_parentContext, pageContext, _jsp__xyz__tag_26, getJspBody(), _jsp_state, _jsp_pageManager));}
...
private _jsp._WEB_22dINF._tags._xyz__tag _jsp__xyz__tag_26;
final _jsp._WEB_22dINF._tags._xyz__tag get_jsp__xyz__tag_26() throws Throwable
{
if (_jsp__xyz__tag_26 == null) {
_jsp__xyz__tag_26 = new _jsp._WEB_22dINF._tags._xyz__tag();
}
return _jsp__xyz__tag_26;
}
In both cases the _jsp._WEB_22dINF._tags._xyz__tag extends com.caucho.jsp.java.JspTagSupport, in 4.0.45 it is not wrapped before the attempt to cast it as javax.servlet.jsp.tagext.Tag
I don't see a way we can work around this issue, thus it is blocking us from upgrading to 4.0.45

A side note/question seems like the SimpleTag instances are now cached, but the documentation https://docs.oracle.com/javaee/5/api/javax/servlet/jsp/tagext/SimpleTag.html [^] states "Unlike classic tag handlers, simple tag handlers are never cached and reused by the JSP container." Is this going to cause problems???
