java.lang.String passed to append/jQuery.clean throws Exception

[joern]

Passing a java.lang.String to jQuery.clean throws a EvaluatorException, caused by/in this line:

if ( arg[0] == undefined || jQuery.nodeName(arg, "form") || arg.options )

Would be nice to find a fix that doesn't require a modification of jQuery.js.

The obvious workaround converts the java String to a native String first: $("...").append("" + javaString)

Typical stacktrace:

Testcode, where getName() returns a java.lang.String:

$("#navmenu").append(blog.getName());

Fixed in [2719] by adding this to the context initalisation:

Context.getCurrentContext().getWrapFactory().setJavaPrimitiveWrap(false);
