It seems jelly-tag:
<j:if test="${!empty(plugin.Transactionmanagerlookup)}">
fails to detect empty properties

Tried with:
<j:if test="${plugin.notEmpty(plugin.Transactionmanagerlookup)}">

public class HibernateConfigPlugin extends AbstractHibernatePlugin {
...
public boolean notEmpty(Object object) {
if (object != null) {
if (object instanceof String) { return ((CharSequence) object).length() > 0; }
return true;
}
return false;
}
...
}

And it generates the config correctly.
