I was having a look in the JConsole at the stack of the hanging thread, I think
the issue is to do with my abstractEntity class (which all the JPA entity
objects extend) overrides the hascode with this...
public int hashCode() {
if(getId() != null)
{
return new HashCodeBuilder().append(getId()).toHashCode();
}
else
{
return HashCodeBuilder.reflectionHashCode(this);
}
When I remove this, the fromXML() works

Hello Dale,
sorry, I was busy yesterday.

It's a general problem with TreeSet/TreeMap (sets use internally typically
maps). If the optimized addAll/putAll does not work, the order of every element
has to be recalculated when they are inserted. This is even worse for
deserialization frameworks, if the compareTo method accesses all kind of other
members that might have not yet been deserialized and operates therefor on
incomplete objects.
The JDK has typically an optimization if you try to put an already sorted map
into an empty one. From the stack trace below, it is visible, that the
condition for the optimization was not met, but I do not understand why.

You may try to use omitField instead.
