Saxon

Hi, Here's an exception we've run across using Saxon 8.7.1. Its a little unusual and we're wondering under what conditions this can occur. E.g. is our code somehow messing up the multithreading environment and causing this. We've tried using 8.9.0.3 but are having other issues with it (as per another stack trace I've posted). Thanks, Jerry java.lang.AssertionError: Value of variable is undefined (null) at net.sf.saxon.value.Value.getIterator(Value.java:227) at net.sf.saxon.expr.VariableReference.iterate(VariableReference.java:211) at net.sf.saxon.expr.PathExpression.iterate(PathExpression.java:767) at net.sf.saxon.expr.PathExpression.iterate(PathExpression.java:767) at net.sf.saxon.expr.ForExpression.iterate(ForExpression.java:519) at net.sf.saxon.value.Closure.iterate(Closure.java:282) at net.sf.saxon.value.Value.getIterator(Value.java:223) at net.sf.saxon.expr.UserFunctionCall.iterate(UserFunctionCall.java:211) at net.sf.saxon.value.MemoClosure.iterate(MemoClosure.java:91) at net.sf.saxon.value.Value.getIterator(Value.java:223) at net.sf.saxon.expr.VariableReference.iterate(VariableReference.java:211) at net.sf.saxon.functions.Existence.effectiveBooleanValue(Existence.java:33) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:244) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.LetExpression.process(LetExpression.java:203) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:245) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:247) at net.sf.saxon.expr.LetExpression.process(LetExpression.java:203) at net.sf.saxon.expr.IfExpression.process(IfExpression.java:245) at net.sf.saxon.expr.ForExpression.process(ForExpression.java:540) at net.sf.saxon.instruct.Block.processLeavingTail(Block.java:338) at net.sf.saxon.expr.LetExpression.processLeavingTail(LetExpression.java:329) at net.sf.saxon.instruct.Block.processLeavingTail(Block.java:336) at net.sf.saxon.instruct.Instruction.process(Instruction.java:91) at net.sf.saxon.instruct.ElementCreator.processLeavingTail(ElementCreator.java:164) at net.sf.saxon.instruct.Block.processLeavingTail(Block.java:336) at net.sf.saxon.instruct.Instruction.process(Instruction.java:91) at net.sf.saxon.instruct.ElementCreator.constructElement(ElementCreator.java:250) at net.sf.saxon.instruct.ElementCreator.evaluateItem(ElementCreator.java:195) at net.sf.saxon.instruct.Instruction.iterate(Instruction.java:312) at net.sf.saxon.instruct.Block$BlockIterator.next(Block.java:409) at net.sf.saxon.query.XQueryExpression$ErrorReportingIterator.next(XQueryExpression.java:521) at net.sf.saxon.query.QueryResult.serializeSequence(QueryResult.java:126)
