I am testing the two variants.
If I use the original variant executeAndWait I get what is the original
error of this thread.
If I use the execute variant I get the new error and apparent double
encoding.
I am not applying any encoding. I just escape the quotes (in both cases):
String htmlText=originalHtml.replace("\"","\\\"");
It has be done because I have to inject the HTML into the srcdoc attribute
of the IFRAMEs.
