OSB thread dump on XQuery parser

 I am logging $body during this Thread Dump.... interesting stuff... OSB internally uses Apache XMLBeans and Apache Piccolo Sax Parser

Also interesting that whenever XQuery wants to read a variable it calls

com/bea/wli/sb/context/MessageContextImpl.getVariableValue(MessageContextImpl.java:202)


I have put in BOLD the focal points.
