More info on subject. While trying to simplify the test case I've started to get different error:

Thanks

The two crashes are actually different manifestations of the same error: a component reference (probably a function call) is attempting to locate the target component using the wrong binding vector. In the first case it finds a component of the wrong type, and crashes with a ClassCastException; in the second case the binding vector is too short, and it crashes with an IOOBE.

(This is all part of the mechanism for implementing separately compiled packages in XSLT 3.0)

What the stack trace doesn't tell us is why. The theory is that whenever a component is invoked, the current component is placed in the context. The crash means that some code somewhere has failed to follow this protocol. To locate the error, we will need a repro. Thanks for your efforts on this. Don't worry if the repro contains a lot of code: so long as it doesn't have complex external dependencies, we should be able to pin it down.

I reduced the problem to a following gibrish xslt:

I hope you can reproduce the problem on your side. Input is any xml.

It results in:

Fatal error during transformation: java.lang.IndexOutOfBoundsException: Index: 1, Size: 1

Thanks for your efforts. I regret my first attempts to reproduce it have been unsuccessful: I get

Type error at argument on line 15 column 30 of crash.xsl: XTTE0570: A sequence of more than one item is not allowed as the value of variable $code (, , ...) in built-in template rule A sequence of more than one item is not allowed as the value of variable $code (, , ...)

Changed the declaration of $code to say as="element()*", and the stylesheet runs to completion without error.

FWIW, it's fairly clear from the stack trace that it's failing at the function call on line 46, where it's evaluating the default value of a local template parameter. Intuitively, that's an easy place for the code to get muddled about what the current component is. In the morning I'll do a careful code-check of that path to see if I can spot anything amiss.

Editor has removed a some tags. Please look into file attached.

Thanks, but it still doesn't fail for me. I get the output

@@

I suspected something like this, as even small changes in that xslt, like removing something that's never called, prevents the error.

I still, can confirm that I can reproduce that problem. I'm using Saxon from maven: http://search.maven.org/#artifactdetails%7Cnet.sf.saxon%7CSaxon-HE%7C9.7.0-5%7Cjar

I've reproduced it now by running with the -T option.

Please track progress on this bug here:

https://saxonica.plan.io/issues/2770

A patch has now been tested and committed.

When can we expect it on maven?

We tend to do a new maintenance release every 4-6 weeks. Can't commit to firm dates.

On you site a couple of days ago you have published that Saxon 9.7.0.6 is available. For some reason I cannot see it on maven. E.g. http://search.maven.org/#search%7Cgav%7C1%7Cg%3A%22net.sf.saxon%22%20AND%20a%3A%22Saxon-HE%22

Can you please check it?

Hi, the maven deployment will be done shortly. Sorry for the delay.
