Description
We are getting NullPointerException , see below. It doesnt give much information about which attribute or specific item it fails. Let us know what could be an issue or how to debug this issue. Can we get source code so we can debug code and see for which element it fails? I have attached our xslt files.

Same xslt works fine version 9, It gives error with 11.6 version
Updated by Michael Kay 10 months ago
Thanks for reporting it. Sorry, I don't see your attachments. Can you try again? Or if you have trouble, send them by email.
If you want diagnostics about where this is happening in your XSLT code, running with the -T tracing option might help.
It might also be worth disabling bytecode generation.

it says forbidden when I attached the file. I doubt I can send out going email with attachment but let me know the email address. Is there any restriction on attaching files? I am trying to attach zip file
Updated by Urvish Amin 10 months ago
just tried with 12.3 version and it's working fine no issue. Strange .....
Updated by Michael Kay 10 months ago
Sorry you're having trouble with attachments, please send them to support@saxonica.com and I will pick them up from there.
It doesn't surprise me particularly that a problem like this should be present in 11.6 and not in 12.3.

Thanks for uploading one module of your stylesheet. To investigate your problem we will need all the modules of your stylesheet, plus a sample source document, and any other details such as stylesheet parameters that need to be set. You may find it most convenient to zip these together into a single file.
I'm not sure what your latest comment starting "New 2017-06-12T05:12:28 2017-06-12T05:12:28" is supposed to tell us. Ah, I see, it was XML, I have edited it to add "code" markup. Now we just need the other stylesheet modules.

- Status changed from AwaitingInfo to Closed
I'm sorry, I'm (very reluctantly) closing this as unresolved, because you haven't been able to supply a repro that enables us to investigate the problem. We don't like having unresolved bugs in the product, so if you are able to put together a repro, please feel free to reopen the issue. It doesn't have to be a simple repro so long as you provide all the resources we need to execute the code and trigger the failure. Obviously the fewer the external dependencies the better.
Updated by Michael Kay 7 months ago
Further log files received by email today. No repro unfortunately, but something to be going on. My email response:
OK, thanks for sending it.
Excuse the fact that this note is a "thread of consciousness" - I'm exploring the problem and examining hypotheses as I write it, and much of this is a "memo to self".
Would I be correct in thinking this is a reopening of https://saxonica.plan.io/issues/6323 ?
The voluminous -T trace isn't useful to us without seeing the stylesheet code you are executing (and even then, it's unlikely to be especially useful).
The only real diagnostic we have here is
Caused by: java.lang.NullPointerException: Cannot invoke "net.sf.saxon.expr.elab.SequenceEvaluator.evaluate(net.sf.saxon.expr.XPathContext)" because "this.argumentEvaluators[i]" is null
at com.saxonica.expr.JavaExtensionFunctionCall.evaluateArguments(JavaExtensionFunctionCall.java:1017)
at com.saxonica.expr.JavaExtensionFunctionCall$JavaExtensionFunctionCallElaborator.lambda$elaborateForPull$0(JavaExtensionFunctionCall.java:1041)
at net.sf.saxon.expr.instruct.ComponentTracer$ComponentTracerElaborator.lambda$elaborateForPull$1(ComponentTracer.java:313)
at net.sf.saxon.expr.elab.EagerPullEvaluator.evaluate(EagerPullEvaluator.java:37)
which tells us that we were calling a reflexive extension function and failed to evaluate one of the arguments. The other thing we know is that it only fails under load, which means it is probably a multithreading problem.
I can also see from the stack trace that you're running using the JAXP TransformerHandler API.
One thing we need to check is that you aren't attempting to run the same TransformerHandler in more than one thread simultaneously. The TransformerHandler isn't thread-safe and you should create a new instance for each transformation (the Templates object, of course, is reusable). It would be good if you could share the Java code you use for firing off the transformation.
However, I note that it has failed in exactly the same place as your previous report at https://saxonica.plan.io/issues/6323#note-6, and this rather suggests a more specific cause. The failure occurs when you are invoking a Java extension function so we need to check that the extension function itself is thread-safe.
Looking at the exact point of failure is often a little unproductive with multithreading problems, because they are often caused by a data corruption where the code that corrupted the data is nowhere near the code that fell over because of the corruption. But I'm going to try anyway.
A point that worries me a little is that the line numbers are about 6 lines out with the actual code I'm looking at. This might be trivial (the IDE adds and removes imports when it feels like it). I've been exploring the commit history but it doesn't give any obvious clues. Two bugs have affected this module, 6166 and 6286, neither is obviously relevant.
Now looking closely at the code, it has some synchronisation, but does it have enough? The code is allocating data in the shared expression tree on first execution, and is failing because the relevant data has not been allocated, so this is an obvious danger area. It looks safe enough, but Java can play nasty tricks:
synchronized(this) { if (argumentEvaluators == null) { allocateArgumentEvaluators(); } } for (int i = 0; i < numArgs; i++) { actualArgs[i] = argumentEvaluators[i].evaluate(c); }
But that call on allocateArgumentEvaluators() shouldn't even be necessary. It should already have been called by then, on a thread-safe path. And the exception method indicates that argumentEvaluators[i[ is null, not that argumentEvaluators itself is null.
I'm now standing back. I can't see what's wrong with the code, but it shouldn't be trying to write to the expression tree on first evaluation of an expression. The elaboration design introduced in 11 was designed to avoid that; the code here isn't fully implementing that design. The expression evaluators should be part of the elaborator, not part of the expression on the expression tree. The elaborator itself is written to the expression tree, but that's in a single place that is very simple and very safe. So in the absence of a repro where I can show that a particular fix actually works, I'm going to try and change the code to behave in a cleaner way and hope that addresses the issue.

11) - Fix Committed on Branch 12, trunk added
- Platforms Java added
I've applied a patch which I think makes the design more robust, so although we haven't got a test case to show that the problem is fixed, I'm going to mark it resolved (which means the patch will be in the next maintenance release).
