ClassCastException during transformation
----------------------------------------
Key: XALANJ-2453
URL: https://issues.apache.org/jira/browse/XALANJ-2453
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: transformation
Affects Versions: 2.7, 2.7.1
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.
Reporter: Christopher Schultz
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:
