Mukul Gandhi commented on XALANJ-2787:
--------------------------------------
[~martin.honnen] There were code improvements committed to Xalan-J's xsl 3 dev
repos branch few minutes ago, related to implementation of XPath 3.1
'intersect' and 'except' operators. You may try running your XSL example by
using latest code available on Xalan-J repos.
Also currently, Xalan-J's XPath 'intersect' and 'except' operator
implementations cannot handle literal sequence argument(s), that your XSL
example in this bug report uses.
The following workaround currently works fine, for your XSL example provided in
this big report (i.e, we can use a variable referring to a literal sequence),
<xsl:variable name="seq" select="(foo, bar)"/>
<xsl:apply-templates select="* except $seq"/>
> java.lang.StackOverflowError with except operator in XSLT 3 code

> This is a bug report on the XSLT 3.0 development branch of Xalan.
