Saxon-EE rejects recursive XQuery function, when there is no license file
Category:
Build and release
Fix Committed on Branch:
9.6
Fixed in Maintenance Release:
Description
This command line XQuery works with Saxon-EE-9.5.1.8, even when there is no license file around:
java net.sf.saxon.Query -qs:"declare function local:fac($n) {if ($n le 1) then 1 else $n * local:fac($n - 1)}; local:fac(7)"
When using 9.6, it is rejected like this
No license file found - running with licensable features disabled
Query processing failed: License file saxon-license.lic not found. Tried in file:/.../saxon-license.lic, and classpath. A license is needed to use Reflexive extension functions
but it does not actually use reflexive extension functions or other licensable features.
- Category set to Build and release
- Status changed from New to In Progress

Thanks for reporting it.
This is not the intended behaviour. The code is written to attempt to load the license file, and to catch the exception if this fails. If the reason for failure is that the license file doesn't exist, it should carry on in "unlicensed" mode (ie. as if running Saxon-HE). But if an invalid or expired license is found, it should fail explaining the reason.
- Status changed from In Progress to Resolved
Sorry, there was misinformation in the previous message. The query "2+2" doesn't fail. I wasn't running what I thought I was running.
The failure actually occurs if there is any function call present where the binding algorithm for function calls considers the possibility that it might be a reflexive extension function. This will include any call to a user-defined function that is not a backwards reference, that is, a forwards reference or a recursive reference.
Source code fixed on the 9.6 and 9.7 branches.
