• Component/s: transformation
• Security Level: No security risk; visible to anyone (Ordinary problems in Xalan projects. Anybody can view the issue.)
• Environment: GNU/Linux 2.6 kernel 32-bit, Sun JRE 1.5.0_13, Xalan 2.7.1 and libs included with the Xalan 2.7.1 distro.

Description

Using an XSLT found in the VectorConverter 1.2 package to convert an SVG document into a VML document, the following exception is generated. I started out using Cocoon, which provides the full stack trace shown below. The command-line use of Xalan shows a less useful message, which is also included below. I will include an example SVG that fails to transform, and I'll see if I'm permitted to attach the XSLT in question from VectorConverter, or if you'll have to go get it yourselves to reproduce (sorry).

First, the CLI message:

file:///path/to/svg2vml.xsl; Line #114; Column #122; org.apache.xpath.objects.XBooleanStatic

Now, the full stack trace provided by Cocoon:
