> Hello,
> Not sure if it is the right mailling list but here we go anyway.
> I am currently using the Entities.java class (well I am using the
> StringEscapeUtils.java which uses that class). Works really good, saved me a
> lot of time. My thanks to the people who wrote it.
> I have encountered a little problems with it taught. Nothing major but I just
> taugth I would share since it migth be of interest to you.
> I have an heavily multithreaded process that runs on a really under powered
> server. All those threads access the StringEscapeUtils.escapeXml() methods
> pretty much at the same time. What happens is that by the time the Second or
> Third Thread calls the StringEscapeUtils.escapeXml() the static initialization
> in the Entities.java class has not completed yet. That block in particular.
> static {
> XML = new Entities();
> XML.addEntities(BASIC_ARRAY);
> XML.addEntities(APOS_ARRAY);
> }
> I don't get a NullPointer so it seems that XML = new Entities() is actually
> being executed before the other Thread starts but the
> XML.addEntities(BASIC_ARRAY) on the other hand is not executed before the
> other
> thread starts. So when the second or third thread calls the
> StringEscapeUtils.escapeXml() it doesn't escape the BASIC_ARRAY or APOS_ARRAY
> entities. To fix it, in my code, I just make sure to call
> StringEscapeUtils.escapeXml() before I start any threads and it solve the
> problems but if anyone is ever to re-work the class this might be something to
> look at.
> Just to share.
> Thank
> David
